Description Vincent Danen 2010-07-09 04:17:46 UTC

A flaw in the handling of the 'Transfer-Encoding' header was found. A
remote attacker could trigger this flaw which would cause subsequent
requests to fail or information to leak between requests. This flaw is
mitigated if Tomcat is behind a proxy as the proxy should reject the
invalid transfer encoding header.

This was fixed in r958977:

http://svn.apache.org/viewvc?view=revision&revision=958977

Upstream 6.0.28 corrects this flaw as noted:

http://tomcat.apache.org/security-6.html

There is no upstream indication that this has been fixed in Tomcat5, however the patches mostly apply (a few rejects) with fuzz.

Comment 4 Vincent Danen 2010-07-09 15:47:38 UTC

Tomcat 5.5.30 is available to fix this flaw:

http://tomcat.apache.org/security-5.html

And the svn revision (patches) to correct it:

http://svn.apache.org/viewvc?view=revision&revision=959428
