Scientific Linux Security Update : mysql on SL5.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A stack-based buffer overflow flaw was found in the user permission
checking code in MySQL. An authenticated database user could use this
flaw to crash the mysqld daemon or, potentially, execute arbitrary
code with the privileges of the user running the mysqld daemon.
(CVE-2012-5611)

A flaw was found in the way MySQL calculated the key length when
creating a sort order index for certain queries. An authenticated
database user could use this flaw to crash the mysqld daemon.
(CVE-2012-2749)

This update also adds a patch for a potential flaw in the MySQL
password checking function, which could allow an attacker to log into
any MySQL account without knowing the correct password. This problem
(CVE-2012-2122) only affected MySQL packages that use a certain
compiler and C library optimization. It did not affect the mysql
packages in Scientific Linux 5. The patch is being added as a
preventive measure to ensure this problem cannot get exposed in future
revisions of the mysql packages.

After installing this update, the MySQL server daemon (mysqld) will be
restarted automatically.
