4.3.2, 4.2.2, 4.0.7, and 3.6.10 Security AdvisoryThursday, Aug 30th, 2012
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: * When the user logs in using LDAP, the username is not escaped before being passed to LDAP which could potentially lead to LDAP injection. * 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 possible. Vulnerability Details ===================== 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. References: https://bugzilla.mozilla.org/show_bug.cgi?id=785470 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.
