Red Hat MySQL Vulnerabilities
[Red Hat Security Advisory RHSA-2003:093-14]
May 2, 2003 17:00 GMT Number N089
______________________________________________________________________________
PROBLEM: Red Hat announces the release of updated MySQL server packages
which fix both a double-free security vulnerability and a root
exploit security vulnerability.
PLATFORM: Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
Red Hat Linux 8.0
Red Hat Linux 9
DAMAGE: These vulnerabilities if exploited could either cause a denial
of service attack or the more serious one, lead to a local user
gaining root.
SOLUTION: Apply patch as instructed in Red Hat's advisory.
______________________________________________________________________________
VULNERABILITY The risk is MEDIUM. By exploiting the double-free vulnerability
ASSESSMENT: in mysqld attackers with MySQL access could cause a denial of
service by creating a carefully crafted client application.
MySQL 3.23.55 and earlier creates world-writable files and
allows mysql users to gain root privileges by using the "SELECT
* INFO OUTFILE" operator to overwrite a configuration file and
cause mysql to run as root upon restart.

Security Advisory
Details:
Updated MySQL server packages fix both a double-free security
vulnerability and a root exploit security vulnerability.
[Updated 1 May 2003]
Added updated packages for Red Hat Linux 9, which is vulnerable to
CAN-2003-0150.
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. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0073 to this issue.
MySQL 3.23.55 and earlier creates world-writable files and allows mysql
users to gain root privileges by using the "SELECT * INFO OUTFILE" operator
to overwrite a configuration file and cause mysql to run as root upon
restart. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2003-0150 to this issue.
All users are advised to upgrade to MySQL 3.23.56 contained within this
errata which is not vulnerable to these issues.
In addition to the security fixes, these erratum packages contain a
thread safe client library (libmysqlclient_r).
