-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. 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 possible. Vulnerability Details ===================== 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. References: https://bugzilla.mozilla.org/show_bug.cgi?id=476594 Vulnerability Solutions ======================= 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.
