"A Bugzilla Security Advisory reports :

- Remote Information Disclosure : 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.

- Notification Bypass : 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.

- Remote Information Disclosure : 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.)

- Denial of Service : 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."
