Severity:normal
Title:MySQL: Denial of Service
Date:11/18/2007
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 Architecture(s)
dev-db/mysql < 5.0.44-r2 >= 5.0.44-r2 All supported architectures

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"
