GLSA-200507-12 : Bugzilla: Unauthorized access and information disclosure

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200507-12
(Bugzilla: Unauthorized access and information disclosure)

Bugzilla allows any user to modify the flags of any bug
(CAN-2005-2173). Bugzilla inserts bugs into the database before marking
them as private, in connection with MySQL replication this could lead
to a race condition (CAN-2005-2174).

Impact :

By manually changing the URL to process_bug.cgi, a remote attacker
could modify the flags of any given bug, which could trigger an email
including the bug summary to be sent to the attacker. The race
condition when using Bugzilla with MySQL replication could lead to a
short timespan (usually less than a second) where the summary of
private bugs is exposed to all users.

Workaround :

There are no known workarounds at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=www-apps/bugzilla-2.18.3'
