[issue44744] [security] Open redirect attack due to insufficient validation in Urlparse

[ready-research]

ready-research  added the comment:

Node.js is recommending using WHATWG URL API. Which handles all these 
correctly. We can test the same using https://jsdom.github.io/whatwg-url/

For example test the below and will return the same(correct) for all. 
https:///www.attacker.com/a/b
https:/www.attacker.com/a/b
https:\www.attacker.com/a/b
https:/\/\/\www.attacker.com/a/b
https:/\www.attacker.com/a/b



```
hrefhttps://www.attacker.com/a/b
protocolhttps:
username(empty string)
password(empty string)
port(empty string)
hostnamewww.attacker.com
pathname/a/b
search  (empty string)
hash(empty string)
```

SUMMARY:
python urlparse() function should also handle all the above in the same way.

RE: a simple question

[Avi Gross via Python-list]

In addition to the other requests for more info on a very ambiguous
question, let me add one. Did the message suggest something worked on an
earlier version and broke with a new version, or did they mean they just
started USING the current version and hoped the version number was
meaningful for the way they probably did not write proper code in the first
place that loads the module(s) they need?

[issue42182] 3.10 Documentation Not Hyperlinking Some Methods

[Andrei Kulakov]

Andrei Kulakov  added the comment:

Something changed between 3.8 and 3.9 so that "bare" references to methods on 
`object` no longer get linked. So for example, :meth:`__bool__` would get link 
to object.__bool__ anchor, but in 3.9+, it should be :meth:`~object.__bool__` 
for the link to be generated.

The case of __enter__ and __exit__ is that inside of contextmanager block, 
Sphinx knows that bare ref should link to contextmanager, but outside of the 
block, it does not, so no link is created.

In 3.8 docs, there are bare refs to __enter__ and __exit__ outside of relevant 
block, so they link to object.__enter__ and object.__exit__, which is of course 
wrong.

See 2nd paragraph below the block: 
https://docs.python.org/3.8/library/stdtypes.html#contextmanager.__exit__

I wasn't able to find why or how in 3.8 it was configured to auto-link bare 
refs to `object`. I looked at make.bat, conf.py and pyspecific.py

Perhaps in 3.8 the entire file was considered / configured a block for `object` 
object?

I will make a PR to fix the links.

[issue44744] [security] Open redirect attack due to insufficient validation in Urlparse

[ready-research]

ready-research  added the comment:

Some other examples to test this behaviour:
urlparse('https:/\/\/\www.attacker.com/a/b')
urlparse('https:/\www.attacker.com/a/b')

## Comparing it to other languages/runtimes

How do other languages and their runtimes work with URL parsing functions?

Here's Node.js, also showing that it is missing the `host` and `hostname`, with 
a similar behavior to the currently reported "buggy" python `urlparse()` one:
```
node
>require("url").parse("https:/\/\/\www.attacker.com/a/b");

Will return

Url {
  protocol: 'https:',
  slashes: true,
  auth: null,
  host: '',
  port: null,
  hostname: '',
  hash: null,
  search: null,
  query: null,
  pathname: '/www.attacker.com/a/b',
  path: '/www.attacker.com/a/b',
  href: 'https:///www.attacker.com/a/b'
}
```
But it is already documented that using Node.js url.parse can lead to security 
issues: 
https://nodejs.org/dist/latest-v16.x/docs/api/url.html#url_url_parse_urlstring_parsequerystring_slashesdenotehost
`Use of the legacy url.parse() method is discouraged. Users should use the 
WHATWG URL API. Because the url.parse() method uses a lenient, non-standard 
algorithm for parsing URL strings, security issues can be introduced. 
Specifically, issues with host name spoofing and incorrect handling of 
usernames and passwords have been identified.`


Here's Ruby, also showing that it is missing the `host` and `hostname`, with a 
similar behavior to the currently reported "buggy" python `urlparse()` one:

```sh
irb(main):001:0> require 'uri'
=> false
irb(main):002:0> uri = URI.parse('https:/www.attacker.com/a/b')
=> #
irb(main):003:0> uri.host
=> nil
irb(main):004:0> uri.hostname
=> nil
irb(main):005:0> uri.scheme
=> "https"
irb(main):006:0> uri.path
=> "/www.attacker.com/a/b"
```

That said, it seems that Ruby throws on other permutations of the bad URL, 
which python does not. For example:

```
irb(main):011:0> other_uri = URI.parse('https:/\/\/\www.attacker.com/a/b')
Traceback (most recent call last):
8: from /usr/bin/irb:23:in `'
7: from /usr/bin/irb:23:in `load'
6: from /Library/Ruby/Gems/2.6.0/gems/irb-1.0.0/exe/irb:11:in `'

 `split'
URI::InvalidURIError (bad URI(is not URI?): 
"https:/\\/\\/\\www.attacker.com/a/b")
```

Same for this other URI, which Ruby does not accept (unlike python, which does 
accept it and returns with a missing host and hostname properties as evident 
earlier in this report):

```
irb(main):012:0> other_uri = URI.parse('https:/\www.attacker.com/a/b')
Traceback (most recent call last):
8: from /usr/bin/irb:23:in `'
7: from /usr/bin/irb:23:in `load'

 `split'
URI::InvalidURIError (bad URI(is not URI?): "https:/\\www.attacker.com/a/b")
```

Let's look at PHP. PHP's parse_url() function behaves much like python, where 
it misses to identify the host property for all 3 examples provided in this 
report:
```
❯ php -a
Interactive shell

php > var_dump(parse_url('https:/\www.attacker.com/a/b'));
array(2) {
  ["scheme"]=>
  string(5) "https"
  ["path"]=>
  string(22) "/\www.attacker.com/a/b"
}
php > var_dump(parse_url('https:/www.attacker.com/a/b'));
array(2) {
  ["scheme"]=>
  string(5) "https"
  ["path"]=>
  string(21) "/www.attacker.com/a/b"
}
php > var_dump(parse_url('https:/\/\/\www.attacker.com/a/b'));
array(2) {
  ["scheme"]=>
  string(5) "https"
  ["path"]=>
  string(26) "/\/\/\www.attacker.com/a/b"
}
php > var_dump(parse_url('https://www.attacker.com/a/b'));
array(3) {
  ["scheme"]=>
  string(5) "https"
  ["host"]=>
  string(16) "www.attacker.com"
  ["path"]=>
  string(4) "/a/b"
}
```

The applicability of this vulnerability
It seems that, there's no direct way of manipulating a python runtime into a 
severe impact simply by sending it a malformed URL.
However, a userland logic implementation that bases its decision on the python 
urlparse() function may introduce a security vulnerability due to the 
unexpected returned values of the function. These vulnerabilities may manifest 
as an SSRF, Open Redirect and other types of

Python comes with "batteries included". However, if 'everything' was
made immediately-available, each of your program[me]s would be very
long. Accordingly, the 'batteries' are kept in what is called "The
Python Standard Library". To use a library it must be import-ed into
your code.

Docs describing the library are available on-line, specifically the
turtle module (and some examples of its use) can be found at:
https://docs.python.org/3/library/turtle.html

Have fun!

[issue44744] [security] Open redirect attack due to insufficient validation in Urlparse

[Logan Jones]

Logan Jones  added the comment:

I don't know if urlparse is actually "mishandling" these URLs.

Looking over RFC 1808 (https://datatracker.ietf.org/doc/html/rfc1808.html) the 
BNF (https://datatracker.ietf.org/doc/html/rfc1808.html#section-2.2) seems to 
support what urlparse is reporting, at least for the first two examples.

I'll try to break down each scenario. Maybe you can help me understand what you 
expect it to report?

https  :   // /www.attacker.com
^  ^  ^
scheme   Net loc Not a valid  
 Delimeter   netloc character, but
 is a valid abs_path beginning
 (according to the spec net_loc
 is allowed to be empty)


https  :  /www.attacker.com/a/b
^ ^
schemevalid abs_path



https  :  \www.attacker.com/a/b
^ ^
scheme   This isn't actually matched
 anywhere in the BNF, so if
 anything maybe a value error
 should have been raised?

[issue44745] Manual for python 3.9.6 will not let me search

[Dennis Sweeney]

Dennis Sweeney  added the comment:

I replicated the issue: downloading the "Windows Help File" (python396.chm) 
from the release page https://www.python.org/downloads/release/python-396/ , 
opening it, and entering a search term (e.g., "tuple") into the search tab 
resulted in a message box pop-up with the message "No topics found."

Doing the same with the corresponding file on prior release pages, (e.g. 
https://www.python.org/downloads/release/python-395/ ) produced in a list of 
search results, and no such pop-up message.

I'm running Windows 10.0.19042 Build 19042.

[issue44719] Incorrect callable object crashes Python 3.11.0a0

Dennis Sweeney  added the comment:

Indeed, I got no crash on main after GH-27313.

I also got no crash on 3.10 after GH-23568. Its backport to 3.9 (GH-24501) 
would have fixed this, but broke the stable ABI and was reverted. This was 
related to bpo-42500.

I'm closing this "fixed". Feel free to re-open if you still see an issue.

Note that the original example posted did not include a "raise IndexError" 
branch in its __getitem__. That was class I was referring to, since the lack of 
an IndexError causes the iteration to continue forever.

As far as I know, nothing has changed about the iteration protocol in 3.10.

[issue44741] Pattern Matching - star subpattern with a subject derived from collections.abc.Sequence

[Steven D'Aprano]

Steven D'Aprano  added the comment:

How is this not a regression? And a very serious one by the sound of it. All 
the examples that are said to go into an infinite loop work fine in 3.9.

(Obviously I can't check the match statement example in 3.9.)

If the Sequence Protocol really has been dropped from Python's execution model, 
shouldn't there be a PEP for such a major change in behaviour? Legacy or not, 
it is still a part of the language.

At the very least, the examples shouldn't swallow the IndexError and go into an 
infinite loop.

Brandt said:

> the destructuring is basically the same as if you had written:
> 
> [x, *w, y] = Seq()
> 
> ...which also hangs.


It works fine in 3.9, with or without inheriting from the Sequence ABC.

# Python 3.9
>>> class A:
... def __len__(self):
... return 5
... def __getitem__(self, i):
... print(i)
... if i < 5:
... return i
... raise IndexError
... 
>>> [x, *y, z] = A()
0
1
2
3
4
5
>>> x, y, z
(0, [1, 2, 3], 4)


Likewise for list(A()), etc.

The __len__ method isn't needed for iteration to work correctly. I just 
included it to match Pierre's example.

Inheriting from collections.abc.Sequence does not change the behaviour.

Still in 3.9:

>>> list(A())
0
1
2
3
4
5
[0, 1, 2, 3, 4]


I think that closing this is as Not A Bug was premature. If this isn't a bug, 
then I have no idea what counts as a bug any longer :-(

[issue42182] 3.10 Documentation Not Hyperlinking Some Methods

[Andrei Kulakov]

Andrei Kulakov  added the comment:

In this case, it appears that ref with tilde and object makes it work in both 
3.10 and 3.11, but with just bare method specified, it doesn't create link in 
both -- so it may be good to try updating it to have tilde  and a ref to obj:


Once an iterator's :meth:`~iterator.__next__` method raises
:exc:`StopIteration`, it must continue to do so on subsequent calls.
Implementations that do not obey this property are deemed broken.


.. _generator-types:

Generator Types
---

Python's :term:`generator`\s provide a convenient way to implement the iterator
protocol.  If a container object's :meth:`__iter__` method is implemented as a
generator, it will automatically return an iterator object (technically, a
generator object) supplying the :meth:`__iter__` and :meth:`~generator.__next__`
methods.

[issue44745] Manual for python 3.9.6 will not let me search

[Matthew Zielinski]

New submission from Matthew Zielinski :

The Manual for python 3.9.6 always says there are no entries. I searched things 
it definitely had, like modules, but it said there were no topics found.

[issue22239] asyncio: nested event loop

[Yury Selivanov]

Yury Selivanov  added the comment:

> nest-asyncio library (https://github.com/erdewit/nest_asyncio)

Seeing that the community actively wants to have support for nested loops I'm 
slowly changing my opinion on this.

Guido, maybe we should allow nested asyncio loops disabled by default?

[issue44739] Tkinter text horizontal scrollbar is not stationary

[E. Paine]

E. Paine  added the comment:

Thank you for reporting this issue. I have personally found this problem to be 
annoying and it is also noted in msg377227. I did a brief bit of research but 
couldn't find an existing ticket on https://core.tcl-lang.org/tk/ticket so 
please feel free to report it there.

I believe it is a side-effect of optimisations the Tk team have made to allow 
the Text widget to have reasonable performance with a large number of lines (so 
I would be surprised if this limitation was not already known by them). Again, 
thank you for reporting this issue, but tkinter is just a thin wrapper around 
Tk so I think the issue here should be closed.

[issue32635] test_crypt segfaults when using libxcrypt instead of libcrypt

[Arfrever Frehtes Taifersar Arahesis]

Arfrever Frehtes Taifersar Arahesis  added the comment:

Geoffrey Thomas:
I agree that including crypt.h only where required is better.
Can you file new bug with patch?


Benjamin Peterson:
I suspect that with crypt.h not included in _cryptmodule.c, crypt() was treated 
by compiler as implicitly declared function (returning 'int'), however real 
crypt() function returns 'char*'.

[issue44741] Pattern Matching - star subpattern with a subject derived from collections.abc.Sequence

[Brandt Bucher]

Brandt Bucher  added the comment:

I agree, Pablo.

The only thing that makes me pause is that, depending on the pattern, 
*sometimes* we use iteration and *sometimes* we use indexing. That might be 
sort of surprising to classes like Seq if you change patterns or major Python 
versions and this thing starts hanging. Hopefully, though, the reason will be 
relatively easy to debug and fix.

Closing as "not a bug".

[issue44741] Pattern Matching - star subpattern with a subject derived from collections.abc.Sequence

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

I don't think there is anything technically wrong here. The Seq class is 
relying on the legacy version of the iterator protocol, which specifies that 
you need to raise IndexError there to stop the iteration.

For instance, this version works:

import collections.abc

class Seq(collections.abc.Sequence):
def __getitem__(self, i):
if i >= len(self):
raise IndexError
return i
def __len__(self):
return 42

match Seq():
case [x, *w, y]:
z = 0
print(z)


Also, one could argue that Seq has exactly the same problem all over the 
language. For instance

>> list(Seq())

will hang

>> [x,*y] = Seq()

will hang

and so on and so forth. So, if I am a user and I am trying to **predict** how 
this would behave based on these two experiments my conclusion would be:

"Anything that tries to iterate on this thing will hang"

I think that whatever we do, we should make it *predictable* and consistency 
across the language, and IMHO only fixing it in pattern matching doesn't make 
it predictable. Being said that, I don't think these use cases justifies a 
major overhaul of how this behaves everywhere.

[issue44741] Pattern Matching - star subpattern with a subject derived from collections.abc.Sequence

[Brandt Bucher]

Brandt Bucher  added the comment:

(Raising the priority to "high" because any decision on this should ideally be 
made before the 3.10 RCs.)

Hm, interesting. This is because we use UNPACK_EX for these patterns, so the 
destructuring is basically the same as if you had written:

[x, *w, y] = Seq()

...which also hangs.

We actually have three implementations for destructuring sequences:
- Using UNPACK_EX, when there is a starred name.
- Using BINARY_SUBSCR, when there is a starred wildcard.
- Using UNPACK_SEQUENCE, when there is no star.

When using your Seq class:
- The first fails by falling into an infinite loop.
- The second works as expected.
- The third fails with a ValueError at runtime (for a length mismatch).

*If* we decide that this is a big enough problem to fix, then I think the 
easiest way of doing it is to use the BINARY_SUBSCR implementation for all 
three paths (we'll just also need to use BUILD_LIST / LIST_APPEND to actually 
collect the starred items). It will simplify the pattern compiler a bit, but I 
imagine it will also come with a performance penalty as well.

In my opinion, I don't think we should rewrite everything to support Seq 
(though my mind isn't made up entirely). Sequences are supposed to be sized and 
iterable, but Seq doesn't really support the iteration protocol correctly (it 
expects the iterating code to stop once the length is exhausted, rather than 
raising StopIteration).

I'm curious to hear opinions on whether we want to actually fix this, though. 
It seems that it will always be possible to write classes like Seq the hack our 
pattern-matching implementation with dubious sequences and mappings, so it 
really comes down to: is supporting classes like Seq worth potentially slowing 
down all other sequence patterns?

[issue44744] [security] Open redirect attack due to insufficient validation in Urlparse

[ready-research]

New submission from ready-research :

`urlparse` mishandles certain uses of extra slash or backslash(such as 
https:/// , https:/, https:\) and interprets the URI as a relative path. 

A userland logic implementation that bases its decision on the urlparse() 
function may introduce a security vulnerability due to the unexpected returned 
values of the function. These vulnerabilities may manifest as an SSRF, Open 
Redirect, and other types of vulnerabilities related to incorrectly trusting a 
URL.

```
from urllib.parse import urlparse
url1=urlparse('https://www.attacker.com/a/b')
url2=urlparse('https:///www.attacker.com/a/b')
url3=urlparse('https:/www.attacker.com/a/b')
url4=urlparse('https:\www.attacker.com/a/b')
print("Normal behaviour: HOSTNAME should be in netloc\n")
print(url1)
print("\nMishandling hostname and returning it as path\n")
print(url2)
print(url3)
print(url4)
```

OUTPUT:
```
Normal behaviour: HOSTNAME should be in netloc

ParseResult(scheme='https', netloc='www.attacker.com', path='/a/b', params='', 
query='', fragment='')

Mishandling hostname and returning it as path

ParseResult(scheme='https', netloc='', path='/www.attacker.com/a/b', params='',

I agree not backporting is most likely fine; just want to add that the issue 
here is that it allows you to enter command for an invalid breakpoint, creating

[issue44743] asyncio DatagramProtocol stops calling callbacks after OSError

[Julian_Orteil]

New submission from Julian_Orteil :

After working through the Transports and Protocols documentation of asyncio, I 
decided to stress test the DatagramProtocol as an application I'm developing 
needs to act as a UDP server.

One of my tests drops the client before the server responds which raises an 
OSError on the server; however, after the error is raised, the server stops 
executing callbacks (like connection_made, datagram_received, error_received 
and connection_lost) until it is restarted. There is no documentation I can 
find that explains this behavior nor is there any meaningful discussions about 
it elsewhere. I don't think the socket itself drops because the client doesn't 
raise an OSError itself when connecting to the now-errored server.

Interestingly though, when I tried to enable debug mode of the loops on both 
the client to see if there were any silent errors being raised (which didn't 
occur), this issue doesn't occur. Enabling debug mode on the server had no 
effect.

Attached is the reproducible code; it is a slightly modified version of the UDP 
Echo Client/Server example found in the docs named above. My environment is 
Python 3.9.5 on Windows 10.

[issue44742] smtplib: less confusing behaviour when giving incorrect multiple recipients list

[Célestin Matte]

New submission from Célestin Matte :

When giving recipients in a string format ("email1, email2") to sendmail(), an 
email is sent to the first email in the list only.
This is not a bug since the documentation indicates that sendmail() takes 
either a list of addresses, or a single address in a string. However, this 
error is easy to make since the "To:" field expects a comma-separated series of 
email addresses in a string format.

I suggest either that:
- sendmail() accepts a series of emails in a string format: "email1, email2" 
for the recipient lists
- sendmail() raises an exception if a series of email in a string format is 
detected

Attached is an example script to test confusing behaviour (email is sent to 
ema...@mydomain.com only):

[issue44741] Pattern Matching - star subpattern with a subject derived from collections.abc.Sequence

[Pierre Quentel]

New submission from Pierre Quentel :

This code

match range(42):
case [x, *w, y]:
z = 0

sets w to a list with 40 items : the length of the subject, minus the number of 
non-star subpatterns.

But this code (adapted from test_patma_186) enters an infinite loop

import collections.abc

class Seq(collections.abc.Sequence):
def __getitem__(self, i):
print('get item', i)
return i
def __len__(self):
return 42

match Seq():
case [x, *w, y]:
z = 0

__getitem__ gets called forever, instead of stopping when the expected number 
of items in w is reached.

When I was working on Tkinter GUI, I made a Text with two Scrollbars. But when 
I created many lines, filled the last line with letters, and then dragged the

dragging down to the end, the Slider of the XScrollbar is not on the far right.
I hope this bug can be fixed as soon as possible.

[issue44738] io_uring as a new backend to selectors and asyncio

[Joongi Kim]

Joongi Kim  added the comment:

As in the previous discussion, instead of tackling stdlib right away, it would 
be nice to evaluate the approach using 3rd-party libs, such as trio and/or 
async-tokio, or maybe a new library.

I have a strong feeling that we need to improve the async file I/O.
AFAIK, aiofiles is the only choice we have and it uses a thread pool, which 
involves many more context switches than required.

[issue44738] io_uring as a new backend to selectors and asyncio

[Joongi Kim]

New submission from Joongi Kim :

This is a rough early idea suggestion on adding io_uring as an alternative I/O 
multiplexing mechanism in Python (maybe selectors and asyncio). io_uring is a 
relatively new I/O mechanism introduced in Linux kernel 5.1 or later.

https://lwn.net/Articles/776703/
https://lwn.net/Articles/810414/
https://blogs.oracle.com/linux/post/an-introduction-to-the-io_uring-asynchronous-io-framework

The advantages of io_uring over epoll:
 - completion-based
 - less number of syscalls
 - higher performance (https://twitter.com/hielkedv/status/1218891982636027905)
 - file I/O support including read/write/stat/open/close

I'm not sure that io_uring would bring actual performance improvements to 
Python (and asyncio) or not yet.
We need some exploration and prototyping, but still technically it would be a 
nice-to-have feature, considering Python's recent speed-up optimizations.
Also io_uring is also intended to support high-speed storage devices such as 
NVMe, and may be a good addition to asyncio in terms of improved async file I/O 
support.

Here are existing attempts to incorporate uring in other languages:
 - liburing (C, https://github.com/axboe/liburing)
 - iou, tokio-uring (Rust, https://tokio.rs/blog/2021-07-tokio-uring)

I don't have any estimation on the efforts and time required to do the work,
but just want to spark the discussion. :)
