Additional info:

This is most likely not exploitable on Fedora, due to FORTIFY_SOURCE protection,
as the overflow is strcat() call which is protected.

According to the Gentoo bug, the CVE identifier for this was requested.
Comment 1 Tomas Hoger 2007-09-27 08:15:15 EDT
CVE name is CVE-2007-4033, which was originally described as php_gd2
vulnerability.  Description on CVE site is already updated.
Comment 2 José Matos 2007-09-27 11:01:49 EDT
I read it here as well
http://lwn.net/Articles/250737/

I am applying the fix and rebuilding for FC-6, F-7 and F-8.
Comment 3 José Matos 2007-09-27 12:18:33 EDT
Build finished for F-7 and F-8. I will issue the build for FC-6 later (due to 
problems with plague and the local firewall).
