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. References: CVE Number: CVE-2012-1968

Class: Information Leak Versions: 2.17.5 to 3.6.9, 3.7.1 to 4.0.6, 4.1.1 to 4.2.1, 4.3.1 Fixed In: 3.6.10, 4.0.7, 4.2.2, 4.3.2 Description: The description of a private attachment could be visible to a user who hasn't permissions to access this attachment if the attachment ID is mentioned in a public comment in a bug that the user can see. References: CVE Number: CVE-2012-1969
