Debian Security Advisory DSA 739-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
July 6th, 2005 http://www.debian.org/security/faq
- - --------------------------------------------------------------------------
Package : trac
Vulnerability : missing input sanitising
Problem-Type : remote
Debian-specific: no
Stefan Esser discovered an input validation flaw within Trac, a wiki
and issue tracking system, that allows download/upload of files and
therefore can lead to remote code execution in some configurations.
The old stable distribution (woody) does not contain the trac package.
For the stable distribution (sarge) this problem has been fixed in
version 0.8.1-3sarge2.
For the unstable distribution (sid) this problem has been fixed in
version 0.8.4-1.
We recommend that you upgrade your trac package.
Upgrade Instructions
