Summary: Update netty to 4.1.61.Final
Key: TEZ-4354
URL: https://issues.apache.org/jira/browse/TEZ-4354
Project: Apache Tez
Issue Type: Improvement
Reporter: D M Murali Krishna Reddy
[https://nvd.nist.gov/vuln/detail/CVE-2019-16869]
Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP
headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP
request smuggling.
[https://nvd.nist.gov/vuln/detail/CVE-2019-20444]
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks
a colon, which might be interpreted as a separate header with an incorrect
syntax, or might be interpreted as an "invalid fold."
[https://nvd.nist.gov/vuln/detail/CVE-2019-20445]
HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to
be accompanied by a second Content-Length header, or by a Transfer-Encoding
header.
[https://nvd.nist.gov/vuln/detail/CVE-2021-21290]
Netty is an open-source, asynchronous event-driven network application
framework for rapid development of maintainable high performance protocol
servers & clients. In Netty before version 4.1.59.Final there is a
vulnerability on Unix-like systems involving an insecure temp file. When
netty's multipart decoders are used local information disclosure can occur via
the local system temporary directory if temporary storing uploads on the disk
is enabled. On unix-like systems, the temporary directory is shared between all
user. As such, writing to this directory using APIs that do not explicitly set
the file/directory permissions can lead to information disclosure. Of note,
this does not impact modern MacOS Operating Systems. The method
"File.createTempFile" on unix-like systems creates a random file, but, by
default will create this file with the permissions "-rw-r--r--". Thus, if
sensitive information is written to this file, other local users can read this
information. This is the case in netty's "AbstractDiskHttpData" is vulnerable.
This has been fixed in version 4.1.59.Final. As a workaround, one may specify
your own "java.io.tmpdir" when you start the JVM or use
"DefaultHttpDataFactory.setBaseDir(...)" to set the directory to something that
is only readable by the current user.

Netty is an open-source, asynchronous event-driven network application
framework for rapid development of maintainable high performance protocol
servers & clients. In Netty (io.netty:netty-codec-http2) before version
4.1.60.Final there is a vulnerability that enables request smuggling. If a
Content-Length header is present in the original HTTP/2 request, the field is
not validated by `Http2MultiplexHandler` as it is propagated up. This is fine
as long as the request is not proxied through as HTTP/1.1. If the request comes
in as an HTTP/2 stream, gets converted into the HTTP/1.1 domain objects
(`HttpRequest`, `HttpContent`, etc.) via `Http2StreamFrameToHttpObjectCodec
`and then sent up to the child channel's pipeline and proxied through a remote
peer as HTTP/1.1 this may result in request smuggling. In a proxy case, users
may assume the content-length is validated somehow, which is not the case. If
the request is forwarded to a backend channel that is a HTTP/1.1 connection,
the Content-Length now has meaning and needs to be checked. An attacker can
smuggle requests inside the body as it gets downgraded from HTTP/2 to HTTP/1.1.
For an example attack refer to the linked GitHub Advisory. Users are only
affected if all of this is true: `HTTP2MultiplexCodec` or `Http2FrameCodec` is
used, `Http2StreamFrameToHttpObjectCodec` is used to convert to HTTP/1.1
objects, and these HTTP/1.1 objects are forwarded to another remote peer. This
has been patched in 4.1.60.Final As a workaround, the user can do the
validation by themselves by implementing a custom `ChannelInboundHandler` that
is put in the `ChannelPipeline` behind `Http2StreamFrameToHttpObjectCodec`.

Netty is an open-source, asynchronous event-driven network application
framework for rapid development of maintainable high performance protocol
servers & clients. In Netty (io.netty:netty-codec-http2) before version
4.1.61.Final there is a vulnerability that enables request smuggling. The
content-length header is not correctly validated if the request only uses a
single Http2HeaderFrame with the endStream set to to true. This could lead to
request smuggling if the request is proxied to a remote peer and translated to
HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did
miss to fix this one case. This was fixed as part of 4.1.61.Final.
There are a couple of critical vulnerabilities in the current netty version
which is being used. It is better to upgrade netty from 4.0.52.Final to
4.1.61.Final
