Description: 
=========================================================== Ubuntu Security Notice USN-274-1 April 27, 2006 mysql-dfsg vulnerability CVE-2006-0903 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) Ubuntu 5.10 (Breezy Badger) The following packages are affected: mysql-server The problem can be corrected by upgrading the affected package to version 4.0.20-2ubuntu1.7 (for Ubuntu 4.10), 4.0.23-3ubuntu2.2 (for Ubuntu 5.04), or 4.0.24-10ubuntu2.1 (for Ubuntu 5.10). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: A logging bypass was discovered in the MySQL query parser. A local attacker could exploit this by inserting NUL characters into query strings (even into comments), which would cause the query to be logged incompletely. This only affects you if you enabled the 'log' parameter in the MySQL configuration.
