Security Advisory for Bugzilla 3.2.1, 3.0.7, and 3.3.2
-----BEGIN PGP SIGNED MESSAGE-----
Bugzilla is a Web-based bug-tracking system, used by a large number of
Bugzilla 3.2.1, 3.0.7, and 3.3.2, when running under mod_perl,
generated insufficiently random numbers, resulting in all random
tokens being the same, all CSRF protection being defeated, and the
new attachment_base functionality being compromised. Only these
releases were affected--earlier releases are not affected.
All affected installations are encouraged to upgrade as soon as
Class: Insufficiently Random Numbers
Versions: 3.2.1, 3.0.7, and 3.3.2
Fixed In: 3.2.2, 3.0.8, 3.3.3
Description: Bugzilla was calling srand() at compile time. Under
mod_perl, this led to all Apache children having the same
random seed, meaning that they all generated identical
"random" strings instead of actually random strings.
This means that all tokens were highly predictable, all
CSRF protection was easily circumvented, and any
installation using the new attachment_base functionality
could possibly have any private attachment viewed without
the user even logging in.
Versions before 3.2.1, 3.0.7, and 3.3.2 were not
affected. Installations that are not using mod_perl
for Bugzilla are not affected.
The fix for this issue in is included in the 3.3.3, 3.2.2, and 3.0.8
releases. Upgrading to a release with the relevant fix will protect
your installation from possible exploits of this issue.

versions, and CVS upgrade instructions are available at:
