From the upstream advisory at $URL: 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: * In HTML bugmails, an improper validation of the permissions of the addressee can lead to confidential information about bugs and attachments to be visible to the addressee. * The description of a private attachment can be visible to a user who hasn't permissions to access this attachment if the attachment ID is mentioned in a comment in a bug. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Information Leak Versions: 4.1.1 to 4.2.1, 4.3.1 Fixed In: 4.2.2, 4.3.2 Description: In HTML bugmails, all bug IDs and attachment IDs are linkified, and hovering these links displays a tooltip with the bug summary or the attachment description if the user is allowed to see the bug or attachment. But when validating user permissions when generating the email, the permissions of the user who edited the bug were taken into account instead of the permissions of the addressee. This means that confidential information could be disclosed to the addressee if the other user has more privileges than the addressee. Plain text bugmails are not affected as bug and attachment IDs are not linkified.

CVE-2012-1969 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1969): The get_attachment_link function in Template.pm in Bugzilla 2.x and 3.x before 3.6.10, 3.7.x and 4.0.x before 4.0.7, 4.1.x and 4.2.x before 4.2.2, and 4.3.x before 4.3.2 does not check whether an attachment is private before presenting the attachment description within a public comment, which allows remote attackers to obtain sensitive description information by reading a comment. CVE-2012-1968 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1968): Bugzilla 4.1.x and 4.2.x before 4.2.2 and 4.3.x before 4.3.2 uses bug-editor permissions instead of bugmail-recipient permissions during construction of HTML bugmail documents, which allows remote attackers to obtain sensitive description information by reading the tooltip portions of an HTML e-mail message.
