Debian 3.0: DSA 483-1 Critical MySQL File Overwrite Threat

Two vulnerabilities have been discovered in mysql, a common database
system. Two scripts contained in the package don't create temporary
files in a secure fashion. This could allow a local attacker to
overwrite files with the privileges of the user invoking the MySQL
server, which is often the root user. The Common Vulnerabilities and
Exposures identifies the following problems:

CAN-2004-0381

The script mysqlbug in MySQL allows local users to overwrite
arbitrary files via a symlink attack.

CAN-2004-0388

The script mysqld_multi in MySQL allows local users to overwrite
arbitrary files via a symlink attack.

For the stable distribution (woody) these problems have been fixed in
version 3.23.49-8.6.

For the unstable distribution (sid) these problems will be fixed in
version 4.0.18-6 of mysql-dfsg.

We recommend that you upgrade your mysql, mysql-dfsg and related
packages.
