mysql - privilege escalation

CAN-2003-0073: The mysql package contains a bug whereby dynamically
allocated memory is freed more than once, which could be deliberately
triggered by an attacker to cause a crash, resulting in a denial of
service condition. In order to exploit this vulnerability, a valid
username and password combination for access to the MySQL server is
required.

CAN-2003-0150: The mysql package contains a bug whereby a malicious
user, granted certain permissions within mysql, could create a
configuration file which would cause the mysql server to run as root,
or any other user, rather than the mysql user.

For the stable distribution (woody) both problems have been fixed in
version 3.23.49-8.4.

The old stable distribution (potato) is only affected by
CAN-2003-0150, and this has been fixed in version 3.22.32-6.4.

For the unstable distribution (sid), CAN-2003-0073 was fixed in
version 4.0.12-2, and CAN-2003-0150 will be fixed soon.

We recommend that you update your mysql package.
