Two Debian Security Advisories:

1. DSA 1208-1 - New bugzilla packages fix several vulnerabilities

2. DSA 1209-1 - New trac packages fix cross-site request forgery

Detail
======

1. Several remote vulnerabilities have been discovered in the Bugzilla
bug tracking system, which may lead to the execution of arbitrary code.

2. 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.

Debian Bug     : 395094 329387

Several remote vulnerabilities have been discovered in the Bugzilla
bug tracking system, which may lead to the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the following
problems:

CVE-2005-4534

    Javier Fernández-Sanguino Peña discovered that insecure temporary
    file usage may lead to denial of service through a symlink attack.

CVE-2006-5453

    Several cross-site scripting vulnerabilities may lead to injection
    of arbitrary web script code.

For the stable distribution (sarge) these problems have been fixed in
version 2.16.7-7sarge2.

For the upcoming stable distribution (etch) these problems have been
fixed in version 2.22.1-1.

For the unstable distribution (sid) these problems have been fixed in
version 2.22.1-1.

We recommend that you upgrade your bugzilla packages.
