MySQL < 4.0.21 mysql_real_connect() Function Remote Overflow

critical Nessus Plugin ID 14319

Language:

Synopsis

The remote database server is affected by a remote code execution vulnerability.

Description

The remote host is running a version of MySQL that is older than 4.0.21.

MySQL is a database that runs on both Linux/BSD and Windows platforms.
This version is vulnerable to a length overflow within it's mysql_real_connect() function. The overflow is due to an error in the processing of a return Domain (DNS) record. An attacker, exploiting this flaw, would need to control a DNS server, which would be queried by the MySQL server. A successful attack would give the attacker the ability to execute arbitrary code on the remote machine.

Solution

Upgrade to MySQL 4.0.21 or newer.
