Synopsis
========

A Denial of Service vulnerability was found in MySQL.

Background
==========

MySQL is a popular multi-threaded, multi-user SQL server.

Affected packages
=================

    -------------------------------------------------------------------
     Package       /   Vulnerable   /                       Unaffected
    -------------------------------------------------------------------
  1  dev-db/mysql      < 5.0.44-r2                        >= 5.0.44-r2

Description
===========

Joe Gallo and Artem Russakovskii reported an error in the
convert_search_mode_to_innobase() function in ha_innodb.cc in the
InnoDB engine that is leading to a failed assertion when handling
CONTAINS operations.

Impact
======

A remote authenticated attacker with ALTER privileges could send a
specially crafted request to a vulnerable database server possibly
leading to a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MySQL users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.44-r2"
