CVE-2010-2791: mod_proxy information leak affecting 2.2.9 only

[Joe Orton <jo...@redhat.com>]

Jeremy Sowden discovered an information leak in mod_proxy affecting 
httpd version 2.2.9 only.  If a timeout occurred reading a response from 
a backend on a persistent connection, the backend connection was not 
closed.  The response could subsequently be read and delivered to an 
unrelated client.

This issue has been assigned CVE name CVE-2010-2791, and is equivalent 
to CVE-2010-2068 (fixed in 2.2.16) but affects httpd on Unix.  The bug 
was fixed* in 2.2.10 but the security impact was not known at the time.

I'll update http://httpd.apache.org/security/vulnerabilities_22.html to 
reflect this shortly.

Regards, Joe

* fix for 2.2.x branch: http://svn.apache.org/viewvc?rev=699841&view=rev
