3.2.7, 3.4.7, 3.6.1, and 3.7.2 Security Advisory

Thursday, Aug 5th, 2010

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
in Bugzilla:

* It was possible to (at least partially) determine the membership
of any group using the Search interface.

* It was possible to use the 'sudo' feature without sending
a notification to the user being impersonated.

* The 'Reports' and 'Duplicates' pages let you guess the name of
products you could not see, due to the error message that was

* For installations using PostgreSQL, specifying "bug X" or
"attachment X" in a comment would deny access to the bug if X was
larger than the maximum 32-bit signed integer size.

All affected installations are encouraged to upgrade as soon as

Vulnerability Details

Class:       Remote Information Disclosure
Versions:    2.19.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2
Fixed In:    3.2.8, 3.4.8, 3.6.2, 3.7.3
Description: An unprivileged user is normally not allowed to view
other users' group membership. But boolean charts
let the user use group-based pronouns, indirectly
disclosing group membership. This security fix
restricts the use of pronouns to groups the user
belongs to.

CVE Number:  CVE-2010-2756

Class:       Notification Bypass
Versions:    2.22rc1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2
Fixed In:    3.2.8, 3.4.8, 3.6.2, 3.7.3
Description: Normally, when a user is impersonated, he receives
an email informing him that he is being impersonated,
containing the identity of the impersonator. However,
it was possible to impersonate a user without this
notification being sent.

CVE Number:  CVE-2010-2757

Class:       Remote Information Disclosure
Versions:    2.17.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2
Fixed In:    3.2.8, 3.4.8, 3.6.2, 3.7.3
Description: An error message thrown by the "Reports" and "Duplicates"
page confirmed the non-existence of products, thus
allowing users to guess confidential product names.
(Note that the "Duplicates" page was not vulnerable
in Bugzilla 3.6rc1 and above though.)

CVE Number:  CVE-2010-2758

Class:       Denial of Service
Versions:    2.23.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2
Fixed In:    3.2.8, 3.4.8, 3.6.2, 3.7.3
Description: If a comment contained the phrases "bug X" or
"attachment X", where X was an integer larger than the
maximum 32-bit signed integer size, PostgreSQL would
throw an error, and any page containing that comment would
not be viewable. On most Bugzillas, any user can enter
a comment on any bug, so any user could have used this to
deny access to one or all bugs. Bugzillas running on
databases other than PostgreSQL are not affected.
