Title: MySQL: Denial of Service
Date: November 18, 2007
Bugs: #198988
ID: 200711-25

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 &quot;&gt;=dev-db/mysql-5.0.44-r2&quot;
