bugs.gentoo.org is running Bugzilla 2.22.7, which reached end-of-life on July 28, 2009, see http://www.bugzilla.org/news/#release34. This means that this installation is vulnerable to all security bugs found since last summer. This seems a good reason to upgrade to Bugzilla 3.4.5, our most stable release.
*** This bug has been marked as a duplicate of bug 213782 ***
LpSolit: we have been backporting security fixes for a long time ;-)
