trac

It was discovered that Trac, a wiki and issue tracking system for
software development projects, performs insufficient validation against
cross-site request forgery, which might lead to an attacker being able
to perform manipulation of a Trac site with the privileges of the
attacked Trac user.

For the stable distribution (sarge) this problem has been fixed in
version 0.8.1-3sarge7.

For the unstable distribution (sid) this problem has been fixed in
version 0.10.1-1.

We recommend that you upgrade your trac package.
