From mkanat at bugzilla.org Fri Aug 6 02:59:07 2010 From: mkanat at bugzilla.org (Max Kanat-Alexander) Date: Thu, 05 Aug 2010 19:59:07 -0700 Subject: [ANN] Security Advisory for Bugzilla 3.2.7, 3.4.7, 3.6.1, and 3.7.2 Message-ID: <4C5B7A7B.6040501@bugzilla.org> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Summary ======= Bugzilla is a Web-based bug-tracking system used by a large number of software projects. The following security issues have been discovered in Bugzilla: * It was possible to (at least partially) determine the membership of any group using the Search interface. * It was possible to use the 'sudo' feature without sending a notification to the user being impersonated. * The 'Reports' and 'Duplicates' pages let you guess the name of products you could not see, due to the error message that was thrown. * For installations using PostgreSQL, specifying "bug X" or "attachment X" in a comment would deny access to the bug if X was larger than the maximum 32-bit signed integer size. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Remote Information Disclosure Versions: 2.19.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: An unprivileged user is normally not allowed to view other users' group membership. But boolean charts let the user use group-based pronouns, indirectly disclosing group membership. This security fix restricts the use of pronouns to groups the user belongs to.

However, it was possible to impersonate a user without this notification being sent. References: https://bugzilla.mozilla.org/show_bug.cgi?id=450013 CVE Number: CVE-2010-2757 Class: Remote Information Disclosure Versions: 2.17.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: An error message thrown by the "Reports" and "Duplicates" page confirmed the non-existence of products, thus allowing users to guess confidential product names. (Note that the "Duplicates" page was not vulnerable in Bugzilla 3.6rc1 and above though.) References: https://bugzilla.mozilla.org/show_bug.cgi?id=577139 https://bugzilla.mozilla.org/show_bug.cgi?id=519835 CVE Number: CVE-2010-2758 Class: Denial of Service Versions: 2.23.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: If a comment contained the phrases "bug X" or "attachment X", where X was an integer larger than the maximum 32-bit signed integer size, PostgreSQL would throw an error, and any page containing that comment would not be viewable. On most Bugzillas, any user can enter a comment on any bug, so any user could have used this to deny access to one or all bugs. Bugzillas running on databases other than PostgreSQL are not affected.

One new development snapshot (3.7.3), one new stable release (3.6.2) and two security updates for the old stable releases (3.4.8 and 3.2.8). Bugzilla 3.6.2 is our latest stable release. It contains various useful bug fixes and security improvements for the 3.6 branch. Bugzilla 3.4.8 and 3.2.8 are security updates for the 3.4 branch and the 3.2 branch, respectively. Bugzilla 3.7.3 is our third unstable development release leading to Bugzilla 4.0. We have done a fair amount of QA on this release. However, QA found many bugs that have not yet been fixed, so this release should not be used in production environments. Development releases exist as previews of the features that a future release of Bugzilla will contain. They also exist for testing purposes, to collect bug reports and feedback. So, if you find a bug in this development release (or you don't like how some feature works) please tell us.

Defect Tracking Systems allow individuals or groups of developers to keep track of outstanding bugs in their product effectively. Most commercial defect-tracking software vendors charge enormous licensing fees. Despite being "free", Bugzilla has many features its expensive counterparts lack. Consequently, Bugzilla has quickly become a favorite of thousands of organizations across the globe, and is widely regarded as one of the top defect-tracking systems available.
