Synopsis
=======
An authenticated user can crash MySQL through invalid parameters to the
date_format function.

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

Affected packages
================
    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  dev-db/mysql      < 4.1.21                              >= 4.1.21

Description
==========
Jean-David Maillefer discovered a format string vulnerability in
time.cc where MySQL fails to properly handle specially formatted user
input to the date_format function.

Impact
=====
By specifying a format string as the first parameter to the date_format
function, an authenticated attacker could cause MySQL to crash,
resulting in 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 --verbose --oneshot ">=dev-db/mysql-4.1.21"
