-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2007.0072 -- [UNIX/Linux] Security Advisory for Bugzilla 2.20.3, 2.22.1, and 2.23.3 5 February 2007 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Bugzilla Publisher: Bugzilla Operating System: UNIX variants (UNIX, Linux, OSX) Impact: Inappropriate Access Access Privileged Data Cross-site Scripting Access: Remote/Unauthenticated - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers two security issues that have recently been fixed in the Bugzilla code: + A possible cross-site scripting (XSS) vulnerability in Atom feeds produced by Bugzilla. + Web server settings given by Bugzilla which provide security settings to protect data files from access via the web are overridden by the mod_perl startup script when running under mod_perl (development snapshot only). We strongly advise that 2.20.x users should upgrade to 2.20.4. 2.22 users, and users of 2.16.x or below, should upgrade to 2.22.2. Versions 2.18.x are not affected by either of these vulnerabilities. Development snapshots of 2.23 before 2.23.4 are also vulnerable to all of these issues. If you are using a development snapshot, you should upgrade to 2.23.4, use CVS to update, or apply the patches from the specific bugs listed below. Vulnerability Details ===================== Issue 1 - - ------- Class: Cross-Site Scripting Versions: 2.20.1 and above Description: Bugzilla does not properly escape some fields in generated Atom feeds, which leads to the potential for cross-site scripting in feed readers that support javascript and properly implement the Atom feed specification. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=367674 Issue 2 - - ------- Class: Database password disclosure Versions: 2.23.3 only Description: Bugzilla development snapshot version 2.23.3 introduced the ability to run Bugzilla under mod_perl on Apache. The mod_perl initialization script included with Bugzilla defines a new <Directory> block in the Apache configuration for the directory containing Bugzilla. This block fails to include permission for .htaccess files to override file access permissions. The .htaccess file shipped with Bugzilla prohibits access by web browsers to read the localconfig file, which contains the username and password for connecting to the database server. If you are not running Bugzilla under mod_perl, then this does not affect you. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=367071 Vulnerability Solutions ======================= The fixes for all of the security bugs mentioned in this advisory are included in the 2.20.4, 2.22.2, and 2.23.4 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/ 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.
