3 September 2012
AusCERT Security Bulletin Summary
Operating System: UNIX variants (UNIX, Linux, OSX)
Impact/Access: Execute Arbitrary Code/Commands -- Existing Account
Access Confidential Data -- Remote/Unauthenticated
CVE Names: CVE-2012-3981
- --------------------------BEGIN INCLUDED TEXT--------------------
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
* When the user logs in using LDAP, the username is not escaped
before being passed to LDAP which could potentially lead to LDAP
* Extensions are not protected against directory browsing by default
and users can view the source code of templates used by the
extensions. These templates may contain sensitive data.
All affected installations are encouraged to upgrade as soon as
Class: LDAP Injection
Versions: 2.12 to 3.6.10, 3.7.1 to 4.0.7, 4.1.1 to 4.2.2,
4.3.1 to 4.3.2
Fixed In: 3.6.11, 4.0.8, 4.2.3, 4.3.3
Description: When the user logs in using LDAP, the username is not
escaped when building the uid=$username filter which is
used to query the LDAP directory. This could potentially
lead to LDAP injection.
CVE Number: CVE-2012-3981
Class: Directory Browsing
Versions: 2.23.2 to 3.6.10, 3.7.1 to 4.0.7, 4.1.1 to 4.2.2,
4.3.1 to 4.3.2
Fixed In: 4.0.8, 4.2.3, 4.3.3
Description: Extensions are not protected against directory browsing
and users can access the source code of the templates
which may contain sensitive data.
Directory browsing is blocked in Bugzilla 4.3.3 only,
because it requires a configuration change in the Apache
httpd.conf file to allow local .htaccess files to use
Options -Indexes. To not break existing installations,
this fix has not been backported to stable branches.
The access to templates is blocked for all supported
branches except the old 3.6 branch, because this branch
doesn't have .htaccess in the bzr repository and cannot
be fixed easily for existing installations without
potentially conflicting with custom changes.
CVE Number: none
The fixes for these issues are included in the 3.6.11, 4.0.8, 4.2.3
and 4.3.3 releases. Upgrading to a release with the relevant fixes will
protect your installation from possible exploits of these issues.
If you are unable to upgrade but would like to patch just the
individual security vulnerabilities, there are patches available for
each issue at the "References" URL for each vulnerability.
Full release downloads, patches to upgrade Bugzilla from previous
versions, and CVS/bzr upgrade instructions are available at:
