Description

A remote overflow exists in MySQL. The MySQL server fails to check the length of a scrambled password used by the 4.1 authentication protocol resulting in a stack overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity
Disclosure: OSVDB Verified

Solution

Upgrade to version 4.1.3 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): rename the 'root' account and apply host based login restrictions.

Note that the 4.0 series of the MySQL server is not affected and does not require an upgrade.
