Vulnerability from csaf_redhat - Published: 2003-04-28 12:53 - Updated: 2025-11-21 17:25
Summary
Red Hat Security Advisory: mysql security update
Severity
Important
Notes
Topic: Updated packages are available that fix both a double-free security vulnerability and a remote root exploit security vulnerability found in the MySQL server. [Updated 11 Aug 2003] Updated mysqlclient9 packages are now included. These were previously missing from this erratum.
Details: MySQL is a multi-user, multi-threaded SQL database server. A double-free vulnerability in mysqld, for MySQL before version 3.23.55, allows attackers with MySQL access to cause a denial of service (crash) by creating a carefully crafted client application. A remote root exploit vulnerability in mysqld, for MySQL before version 3.23.56, allows MySQL users to gain root privileges by overwriting configuration files. Previous versions of the MySQL packages do not contain the thread safe client library (libmysqlclient_r). All users of MySQL are advised to upgrade to these errata packages containing MySQL 3.23.56.
