Several vulnerabilities were discovered in Request Tracker (RT), an issue tracking system.
Authenticated users can add arbitrary headers or content to mail generated by RT.
A CSRF vulnerability may allow attackers to toggle ticket bookmarks.
If users follow a crafted URI and log in to RT, they may trigger actions which would ordinarily blocked by the CSRF prevention logic.
Several different vulnerabilities in GnuPG processing allow attackers to cause RT to improperly sign outgoing email.
If GnuPG support is enabled, authenticated users can create arbitrary files as the web server user, which may enable arbitrary code execution.
Please note that if you run request-tracker3.8 under the Apache web server, you must stop and start Apache manually. The restart mechanism is not recommended, especially when using mod_perl.
For the stable distribution (squeeze), these problems have been fixed in version 3.8.8-7+squeeze6.
For the unstable distribution (sid), these problems have been fixed in version 4.0.7-2 of the request-tracker4 package.
We recommend that you upgrade your request-tracker3.8 packages.
