MySQL Community Server < 5.1.47 / 5.0.91 Multiple Vulnerabilities

Medium

Synopsis

The remote database server is vulnerable to multiple attack vectors.

Description

Versions of MySQL server earlier than 5.1.47 / 5.0.91 are potentially affected by the following vulnerabilities :

- The server may continue reading packets indefinitely if it receives a packet larger than the maximum size of one packet, which could allow an unauthenticated remote attacker to consume a high level of CPU and bandwidth. (Bug #50974)

- Using an overly long table name argument to the 'COM_FIELD_LIST' command, an authenticated user can overflow a buffer and execute arbitrary code on the affected host. (Bug #53237)

- Using a specially crafted table name argument to 'COM_FIELD_LIST', an authenticated user can bypass almost all forms of checks for privileges and table-level grants. (Bug #53371)

Solution

Upgrade to MySQL Community Server 5.0.91, 5.1.47, or later.
