Gentoo Linux Security Advisory

Title: Bugzilla: Unauthorized access and information disclosure (GLSA 200507-12)
Severity: low
Exploitable: remote
Date: July 13, 2005
Bug(s): #98348
ID: 200507-12

Synopsis

Multiple vulnerabilities in Bugzilla could allow remote users to modify bug flags or gain sensitive information.

Background

Bugzilla is a web-based bug-tracking system used by many projects.

Affected Packages

Package: www-apps/bugzilla
Vulnerable: < 2.18.3
Unaffected: >= 2.18.3
Architectures: All supported architectures


Description

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.

Resolution

All Bugzilla users should upgrade to the latest available version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/bugzilla-2.18.3"
