Synopsis
========
Trac is vulnerable to a cross-site scripting attack that could allow
arbitrary JavaScript code execution.
Background
==========
Trac is a minimalistic web-based project management, wiki and bug
tracking system including a Subversion interface.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

1 www-apps/trac < 0.9.3 >= 0.9.3
Description
===========
Christophe Truc discovered that Trac fails to properly sanitize input
passed in the URL.
Impact
======
A remote attacker could exploit this to inject and execute malicious
script code or to steal cookie-based authentication credentials,
potentially compromising the victim's browser.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Trac users should upgrade to the latest available version:
