4.3.1, 4.2.1, 4.0.6, and 3.6.9 Security Advisory
Thursday, July 26th, 2012
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
* 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
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 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.
CVE Number: CVE-2012-1969
