MySQL: Multiple vulnerabilities

Background

MySQL is a fast, multi-threaded, multi-user SQL database server.

Description

MySQL fails to properly validate input for authenticated users with INSERT and DELETE privileges (CAN-2005-0709 and CAN-2005-0710). Furthermore MySQL uses predictable filenames when creating temporary files with CREATE TEMPORARY TABLE (CAN-2005-0711).

Impact

An attacker with INSERT and DELETE privileges could exploit this to manipulate the mysql table or accessing libc calls, potentially leading to the execution of arbitrary code with the permissions of the user running MySQL. An attacker with CREATE TEMPORARY TABLE privileges could exploit this to overwrite arbitrary files via a symlink attack.

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-4.0.24"
