Security Advisory for Bugzilla 2.20, 2.21.1, and 2.18.4 Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers three security bugs that have recently been discovered and fixed in the Bugzilla code: + The 'whinedays' and 'mostfreqthreshold' parameters are not correctly validated in editparams.cgi. The first one can lead to SQL injection. + Escaped HTML markup in titles of RSS feeds are incorrectly decoded by some RSS readers and could potentially lead to XSS vulnerabilities. + The login form on the home page, in conjuction with very specific configuation settings and a specially formed URL, may redirect you outside the Bugzilla installation, allowing the login name and password to be stolen. All Bugzilla installations are advised to upgrade to the latest stable version of Bugzilla, 2.20.1. Development snapshots of 2.21 before 2.22rc1 are also vulnerable. If you are using a development snapshot, you should upgrade to 2.22rc1, use CVS to update, or apply the patches from the specific bugs listed below. None of these vulnerabilities affect the old Bugzilla 2.16.x versions. Vulnerability Details ===================== Issue 1 ------- Class: SQL injection Versions: 2.17.1 and above Description: The 'whinedays' parameter, editable from editparams.cgi, is not validated before being saved. This can lead to SQL injection in the whineatnews.pl script. This injection requires administrative privileges. The validation for the 'mostfreqthreshold' parameter is also missing, but this is not exploitable. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=312498 Issue 2 ------- Class: Cross Site Scripting Versions: 2.20rc1 - 2.20, 2.21.1 Description: Some RSS readers incorrectly decode escaped HTML markup in feed titles and this could be used to inject some scripts. Although this is not a Bugzilla bug, we prefer to shift to Atom feeds, where the RFC is unambiguous about HTML markup in feed titles. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=313441 Issue 3 ------- Class: Sensitive Data Exposure Versions: 2.19.3 and above Description: When the Bugzilla login page is at a subdirectory of the web server and the subdirectory name is a resolvable host on the victim's local network, it is possible to craft a URL that, when used to login to Bugzilla, would send the user's credentials to this host. These conditions make this flaw very difficult to exploit. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=325079 Vulnerability Solutions ======================= The fixes for all of the security bugs mentioned in this advisory are included in the 2.18.5, 2.20.1, and 2.22rc1 releases. Upgrading to these releases will protect installations from possible exploits of these issues. Full release downloads, patches to upgrade Bugzilla from previous versions, and CVS upgrade instructions are available at: http://www.bugzilla.org/download.html Specific patches for each of the individual issues can be found on the corresponding bug reports for each issue, at the URL given in the reference for that issue in the list above.

2.18.5 and 2.20.1 in CVS. 2.18.5 needs arch lovin'.
stable on ppc64
Just so those aware dont bug me...I know about the release, I'm on the bugzilla announce ML. I dont use the ebuild for bugs.gentoo.org because I hack at it a ton. Hopefully I can begin test this locally in the next coming days->week and try to schedule some downtime before I take another vacation in a few weeks.
Adjusting status
ppc stable
sparc stable.
amd64 stable
x86 done
Stable on alpha.
Ready to vote. I tend to say no. SQL injection requires admin privileges, and the other two are quite lame.
* DerCorny seconds the no.
Closing, feel free to reopen if you intended to vote yes.
