[/snip] Please explain this, how does it make it more exploitable? I think that this is only true if the code is sloppy. Correct, if you properly initialize your internal variables there is nothing insecure about leaving register_globals on. But how you know, if you have a few tausends of php code lines, which part have some sloppy code. Nobody is perfect. In my opinion you should turn register_globals to off if it's possible. It's much more secure. I strongly disagree with that. Consider the following code (assuming $foo is 'external' variable): 1: if ($foo=='yes') transfer_money_to_me(); 2: if ($_GET['foo']=='yes']) transfer_money_to_me(); Why (2) is safer than (1)? Answer: It is *not*. As Rasmus has correctly pointed out, the usage of register_globals=off per se cannot be considered a security measure. If you don't initialize and/or check *all* user-supported variables, you're dead. It's as simple as that. Is it annoying? Maybe. Is it necessary? *yes* Anyway, IIRC the whole issue of register_globals started when some guy presented a paper named A Study in Scarlet. A whole lot of issues where presented in that paper, which in my opinion, have been blown quite out of perspective. register_globals is one of them. Oh boy, this is starting to look like an urban myth : -Hey do you know that register_globals=on is bad? - Really? -Yeah, and you know what?

While I agree that it doesn't improve security much if the coder was already using $HTTP_SESSION_VARS (which he/she should have been doing), it definitely does not promote lazy programming. If anything, registering all the variables as global promotes lazy programming! Sure, it's convenient to be able to access a variable with this shorter method, but do you really want all of these different session variables, post variables, get variables, cookie variables, and server variables sharing the same global namespace/scope? (I use that last term loosely.) Preventing namespace pollution...now you convince me. I used the term lazy programming without explaining what I meant, hence the misunderstanding. I refer to lazy programming in the sense of not properly and thoroughly checking user input, or as I believe, any input from external to you code sources. If you don't do that I don't believe that anything will save you. Promoting superglobals as a security enhanchment, no I don't buy that. -Stathis.

It doesn't break old functionality. You just have to read the manual.

Firewalls encourage lazy programming! Locks and police encourage lazy domestic vigilance! It's just that I don't see any security value in superglobals.

Re: [PHP] Loading Images
As long as preventing users to download a picture you display, my .02Eu opinion is that is is a fruitless task. A determined user will _always_ find a way to store the picture you send him. After all, you do send data to him, therefore the data can be manipulated at will:-) As far as some code to do it, see attached souce. In the attached source, modify directories as needed. Invoke with : php -q gif2function.php test.php Then point your browser to test.php. warning: Select a dir with few images.

Kevin Stone wrote: Huh.. hmm.. maybe this is possible after all. I'll have to test that out when I get home. If it works it could sure save me a headache or two. By the way most counters/trackers that I've seen are just simple javascripts which gather the browser information then request a tiny image from the server with the information in the URL string. This all goes into the server's standard log file. Then to count the hit the server just reads the log file and parses out the values in the URL string.

At the moment, I'm just storing my images in my file system, and storing the URLs in my database (as discussed by someone else in this thread), which works fine, as long as nobody deletes the image without deleting the URL from the DB. On the topic of preventing users from saving images, the attempts are futile, because they can also just look at your source to DL the image from it's URL. One thing I have seen work instead of disabling right-click is to have a clear layer (DIV) above the whole page, which (for me) prevents me from selecting text + images from below.

You can find tutorials about this online (sorry I don't have any direct links). There are also numerous FREE scripts pre-written that you can integrate into your site, or use to learn how to do this yourself. There is a catch however... and that is you will not be able to display anything else along with those images because special content headers must be sent to let the browser know what kind of data it's receiving. Is it a JPEG, GIF or PNG? If the headers are not sent, or the wrong headers are sent, the image will either not display or the user will see endless rows of junk text spewed onto the screen (the binary data in ASCII form!!). So this method will only work if you want to display the images in a frame, one at a time, and by them selves.

Despite the fact that PHP's WDDX functions don't support a "binary" type,
most binary data comes through just fine, and in fact, the WDDX serialize

But the deserialize process dos not retain these characters. Is this a
bug in PHP's implementation of WDDX, or is there perhaps a workaround
available?
Here's some example code that shows a WDDX packet of encoded binary data.
The packet itself contains all of the binary data, including null
characters, etc. The deserialized() string, however, does not.

PHP/Ora with persitent connections does not work. Explanation. Using OciPlogon you connect to Ora and everything is fine. yep. Then you issue an OciLogout and you terminate your connection as fas as PHP is concerned. wrong Unfortunately, the connection to Oracle is not closed, as a "ps -ef | grep oracle" can tell you. yes - cause PHP will reuse it! Next time PHP is called, OciPlogon requests (and gets) a new connection nope. that would be a bug. I am not aware of the internals, but the displayed behaviour when using OciPLogon is exactly the same with the one displayed when you "forget" to OciLogout. I assume that a new connection is made, since I cannot find another explanation for the number of open connections to increase. I measure open connections doing "ps -elf | grep oracle | grep tnslsnr". to Oracle without using the old one or closing it. Then OciLogout is called and you are now left with two open connections to Oracle. please send me a "minimal" testcase that shows this behaviour! i'll look into that then. OK, I will do so. Expect it some time in Monday. The connections PHP opens will timeout eventually and close "by themselves". nope - that would be bug. I don't think so. All connections to Oracle will close if left by themselves. Oracle will kill them...I think. Now, if you are testing on a personal machine or your machine has enough resources, this problem (that I call "lingering connections") may pass unnoticed. The moment you get more than about 10 hits, those "lingering connections" will add up and pretty soon you will (a) run out of Ora cursors or (b) run out of resources. When that moment comes you will not be able to connect to Ora anymore, untill some of those connections die, which of course is dependant on the timeout. Now in development server with 1GB of RAM (Solaris/Ora.8.0.4.EE/PHP.4.0.3.pl1) the "lingering connections" phenomenon rarely manifestated itself. In fact it was so rare that I almost always suspected my code doing something nasty. When it was moved into production (in a Suse Linux.2.2.14/PHP.4.0.3.pl1/Ora.8.0.5.EE) with only 128MB of RAM, upon the first test run it blew into my face. After changing all OciPlogon into plain OciLogon, all problems dissapeared. This has happened with other applications that I have experimented with. The "lingering connections" problem is with us at least since PHP.3.0.12 (which the first version of PHP I tried). That's why I say that PHP/Ora with *persistent* connection do not play well with each other. i'm the author of this module and more than willing to help. i do tests using the ab tool and have never found any irregularities in the plogon mode. if you can show me how to reproduce this i'm (mostly) sure i can fix it!

me:-)
So, I ran my test case and these are my findings, alogn with the test.
Machine Configuration
Software:
- Apache.1.3.12:httpd.conf:MaxClients 150
- OS:SuSE.Linux.6.4 (2.2.14)
- Ora:Oracle.8.1.6.ee (default install)
I believe that by default you have 50 cursors per connection
without even looking at the rest:
if MaxClients is higher than the number of sessions oracle
allows - you are toasted!
Yes, I understand this.
But in my test case below, I never requested more than 50 connections to
oracle.
The problem is there even if you request 20 connections, provided that
you run the test script in quick succession and do not wait for the
oracle connections to die.
That is, if you:
bash
while [-f file]; do
ab -n 100 -c 20 url
done
/bash
after a while you will get failed requests.
MaxClients 150, ensures that I do not run out of Apache childs and that
the failed requests are indeed due to ora conditions.
you have to expect _one_ persistent connection to each
oracle-instance you connect to per running apache child! in
your case expect up to 150 single connection. if you cannot
support 150 single connection to your oracle-server - a)
decrease MacClients -or- b) up your oracle-session limit!
please get back to me if this is indeed your problem - i'll
investigate further after that!
(i'll look thru the rest of your mail when i find some time -
sorry, just getting up)
No problem, I can wait.

Test case (PHP script)
This code is typical of the way I handle connections to Oracle (except
that I use OciLogon instead of OciPLogon)
code
?php
$oraconnections[0] = '';
$orastatements[0] = '';
function newOracleConnection() {
global $oraconnections;
$c = ociplogon("scott","tiger","oracle");
$oraconnections[] = $c;
return $c;
}
function newOracleStmt($connection, $select, $execute) {
global $orastatements;
$c = ociparse($connection, $select);
$orastatements[] = $c;
if (strtoupper($execute)=='EXECUTE') { ociexecute($c); }
return $c;
}
function cleanup() {
global $orastatements, $oraconnections;
reset($orastatements);
while (list($key,$val)=each($orastatements)) @OciFreeStatement($val);
reset($oraconnections);
while (list($key,$val)=each($oraconnections)) @OCILogoff($val);
}
$cone = NewOracleConnection();
$cone2 = NewOracleConnection();
$cone3 = NewOracleConnection();
$s = "select table_name t from user_tables";
$stmt = NewOracleStmt($cone,$s,'');
OciDefineByName($stmt,strtoupper('t'),$t);
OciExecute($stmt);
while (OciFetch($stmt)) echo "\n table_name=$t";
OciFreeStatement($stmt);
// -- in case we forget
cleanup();
echo "\n";
?
/code
The above code runs in a separate window ("test-w") using the following
command:
ab -n 1000 -c 50 http://aspasia.mm.di.uoa.gr/~rouvas/testora.php
In another window (lets call it "monitor") the following runs in bash:
bash
while [ -f afiedt.buf ]; do
echo -n httpd: `ps -elf | grep httpd | wc -l`;
echo -en " "oracle: `ps -elf | grep oracle | wc -l`;
uptime;
done
/bash
At the beginning, monitor displays something like:
httpd: 6 oracle: 15 1:50am up 8 days, 5:38, 8 users, load average:
1.33, 1.95, 3.49
From now on, I will refer to "httpd: 6" and "oracle: 17" parts of the
above message as "httpd-counter" and "oracle-counter" respectively.
Let the test begin!
Everything is happening on the same machine.
Since I have not recorded all number I will show only significant ones,
that is those that caused troubles. The rest will be displayed as dashes
("-").
ab -n n1 -c n2 url httpd-counter oracle-counter Failed requests
500 10- - 0
500 20- - 0
900 50- ~52 0
The last did not cause any troubles, but... it took a long time for
these oracle processes to die.
So, I rerun the last invocation (900,50) three times serially, i.e. I
waited for the previous one to finish before I fired the next one.
900 50- ~48 0
900 50 ~67 many

Re: [PHP] Oracle Database keeps disconnecting - or something
Do you experience any other sort of problems other than those warnings? I mean, is anything wrong with the data? Normally, nothing should be wrong. I have seen the same messages (especially the "service handle not intitialized" one) in my server too. I have traced it to attemtps to close an already closed connection, as in $cone = OciLogon(...); ...stuff... OciLogout($cone); ...stuff...

Persistent connections and PHP/Ora do not play well with each other. ??? - please elaborate. PHP/Ora without persistent connections are fine and rock solid even under heavy load. PHP/Ora with persitent connections does not work. Explanation. Using OciPlogon you connect to Ora and everything is fine. Then you issue an OciLogout and you terminate your connection as fas as PHP is concerned. Unfortunately, the connection to Oracle is not closed, as a "ps -ef | grep oracle" can tell you. Next time PHP is called, OciPlogon requests (and gets) a new connection to Oracle without using the old one or closing it. Then OciLogout is called and you are now left with two open connections to Oracle. The connections PHP opens will timeout eventually and close "by themselves". Now, if you are testing on a personal machine or your machine has enough resources, this problem (that I call "lingering connections") may pass unnoticed. The moment you get more than about 10 hits, those "lingering connections" will add up and pretty soon you will (a) run out of Ora cursors or (b) run out of resources. When that moment comes you will not be able to connect to Ora anymore, untill some of those connections die, which of course is dependant on the timeout. Now in development server with 1GB of RAM (Solaris/Ora.8.0.4.EE/PHP.4.0.3.pl1) the "lingering connections" phenomenon rarely manifestated itself. In fact it was so rare that I almost always suspected my code doing something nasty. When it was moved into production (in a Suse Linux.2.2.14/PHP.4.0.3.pl1/Ora.8.0.5.EE) with only 128MB of RAM, upon the first test run it blew into my face. After changing all OciPlogon into plain OciLogon, all problems dissapeared. This has happened with other applications that I have experimented with. The "lingering connections" problem is with us at least since PHP.3.0.12 (which the first version of PHP I tried). That's why I say that PHP/Ora with *persistent* connection do not play well with each other. I hoped I cleared the issue. I really hope that this problem is resolved, since I expect an increase in performance when the penalty for making a new connection is avoided. -Stathis. tc -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

So, I rerun the last invocation (900,50) three times serially, i.e. I
waited for the previous one to finish before I fired the next one.
900 50- ~48 0
900 50 ~67 many
900 50 ~65 many
Next I fired up the following from three different windows
simultaneously (almost)
ab -n 1000 -c 50 url
In the first run: http-counter: -
oracle-counter : (below 50)
failed requests : (none)
I waited until http-counter:7 and oracle-counter:17 and rerun the three
simultaneous invocations.
httpd-counter : -
oracle-counter : 52
failed-requests : (none)
Without waiting, I fired the three invocations again.
httpd-counter : 75 (max)
oracle-counter : 82 (max)
failed-requests: 550 (test-w-1), 544 (test-w-2) and 493 9 9(test-w-3)
After more runs (and to make a long story short), I observed that no
matter what the concurrency level or the number of requests to the ab
were, if oracle-counter reached about 55, no more requests would be
served.
That, of course, is consistent with the number of Oracle cursors
available.
What is not consistence, hence I think that OciPlogon is unsuitable in
its current implementation, is that while it proved extremely difficult
to run out of connections within a *single* invocation of my test script
with ab, it was trivial to do so when either (a) you invoke ab without
waiting enough time for the oracle-counter (number of Oracle processes)
to decrease or (b) you do parallel invocations.
Of course, (b) is to be expected. But I didn't expect (a).
If a small number of concurrency(10) is used, (a) is rather difficult to
achieve.
Almost any number bigger than that will raise the problem.
I would expect, that in (a) (serial invocations), PHP to reuse existing
connections and the oracle-counter to remain relatively constant.
Instead, it gradually increases, untill it reaches

Is there any way to pass parameters with php without using the
classic http://www.whatever.com/somepage.php?param=3 type format? So
that the url would look more like
In httpd.conf, in the VirtualHost block for the site:
Location /ThisIsAProgram
ForceType appllication/x-http-php
/Location
In a php program file, named ThisIsAProgram in the DocumentRoot of the
site:
==
?
$Params = explode( '/', $PATH_INFO );
while( list( $Index, $Value ) = each( $Params )) {
echo "Params[ $Index ] = $ValueBR\n" );
}
?
==
Hit this URL:
http://whatever.site.com/ThisIsAProgram/these/directories/are/not/real
You should get:
Params[ 0 ] =
Params[ 1 ] = these
Params[ 2 ] = directories
Params[ 3 ] = are
Params[ 4 ] = not
Params[ 5 ] = real
If you can't or don't want to do the Location thing, you can name the
file ThisIsAProgram.php (or .php3) and call it:
http://whatever.site.com/ThisIsAProgram.php/these/directories/are/not/re
al
But I think it is pretty cool to make the program name look like just
another directory in the tree, so I usually use Location.

Re: [PHP] PHP and Oracle Zombie processes
If you don't see --enable-sigchild in phpinfo() then :
(a) you are not running the version you compiled
(b) your config script had something wrong.
Baseline: if you don't see it, it's not there.
You have to recompile.

When I execute an sql statement against my Oracle database from PHP, I
create an oracle zombie process. This eventually hits a "number of
zombie process" limit and prevents my page from executing.
The queries work properly (except for the zombie problem).
Here is a sample that creates the zombie process:
putenv("ORACLE_HOME=/h/app/oracle/product/8.1.6");
putenv("ORACLE_SID=dbase_name");
putenv("TNS_ADMIN=/h/app/oracle/product/8.1.6/network/admin");//
thought this might help the zombie problem
$conn=OCILogon("get_rid_of" , "zombie");
$sql_get_info="SELECT OppID, OppTitle FROM TEST WHERE OppID=4";
$stmt = OCIParse($conn,$sql_get_info);
OCIExecute($stmt);
OCIFetch($stmt));
$valid_opp_id = OCIResult($stmt, "OPPID");
$valid_opp_title = OCIResult($stmt, "OPPTITLE");
OCIFreeStatement($stmt);
/ using a separate query to get the clob..
$clob_field="OPPTEXT"; // this field in UPPPER CASE
$sql="SELECT $clob_field from TEST WHERE OppID=$oid";
$stmt = OCIParse($conn, $sql);
$clob_text = OCINewDescriptor($conn,OCI_D_LOB);
OCIDefineByName($stmt, $clob_field, $clob_text);
OCIExecute($stmt);
OCIFetch($stmt);
$valid_text=$clob_text-load();
$clob_text-free();
OCIFreeStatement($stmt);
Here is how I configured PHP 4.0.3pl1 (this is from phpinfo();) :
./configure --with-apxs=/usr/local/apache/bin/apxs
--with-config-file-path=/etc/httpd
--with-oracle=/ora8/m01/app/oracle/product/8.1.6
I also added OCI8 support via..
--with-oci8=/ora8/m01/app/oracle/product/8.1.6 ... phpinfo(); states
oci8 support is "enabled".
I did --enable-sigchild but I don't see it showing in the phpinfo();
???
I am using: Oracle 8.1.6, Apache 1.3.12 , RedHat 6.0 - all on one
server.
Any ideas on what I might be doing wrong? Am I missing something? Any
help would be greatly appreciated.
Thanks,
Bob

Re: [PHP] PHP/Oracle mod
From your mail, I understand that you cannot proceed past the compilation step. I've seen the same on previous versions of PHP for Linux, but now this is solved. Maybe the Solaris version didn't got the same fixes... Anyway, PHP will look at ORACLE_HOME for the required libraries which has now different semantics for Oracle. Now(Ora.8i.later) ORACLE_BASE points to old (Ora.8.0.xx) ORACLE_HOME. The new ORACLE_HOME should be $ORACLE_BASE/product/8.1.6 (or whatever version you have). Hope this helps. -Stathis. rbradley wrote: I'm really struggling configuring the php mod with oracle 8i support on Solaris 8. ./configure --enable-track-vars --with-o8ci=/export/home/oracle --with-oracle --enable-sigchild --with-apxs The ORACLE_HOME is set to /export/home/oracle.

Re: [PHP] Shared Memory with Yast-installed mod_php4 from SuSE.
Hit Thomas, you need to recompile PHP with the options you want (as a shared apache module) and then replace libphp4.so on /usr/lib/apache/ with your own version. A good thing is to keep SuSE's version as a backup:-) Don't forget to restart apache afterwards. (/etc/rc.d/apache stop; /etc/rc.d/apache start) A SuSE.6.4 user. -Stathis.
