3.0.4, 3.1.4, and 2.22.4 Security AdvisoryAugust 12, 2008
Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers a security issue that has recently been fixed in the Bugzilla code: * Local files on the server can be attached to a bug (making them publicly visible) when importing bugs with --attach_path All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Directory Traversal Versions: 2.22.1 - 2.22.4, 2.23.3 and higher Description: When importing bugs using importxml.pl, the --attach_path option can be specified, pointing to the directory where attachments to import are stored. If the XML file being read by importxml.pl contains a malicious <data encoding="filename">../relative_path/to/local_file</data> node, the script follows this relative path and attaches the local file pointed by it to the bug, making the file public. The security fix makes sure the relative path is always ignored. Most Bugzilla installations will not be vulnerable, as they do not use --attach_path with importxml.pl. (In fact, most installations don't use importxml.pl at all.) Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=437169 Vulnerability Solutions ======================= The fix for the security bug mentioned in this advisory is included in the 3.2rc1, 3.0.5, and 2.22.5 releases. Upgrading to these releases will protect installations from possible exploits of this issue.
