TITLE:
MySQL "dispatch_command()" Denial of Service Vulnerability

SECUNIA ADVISORY ID:
SA35767

VERIFY ADVISORY:
http://secunia.com/advisories/35767/

DESCRIPTION:
Nikolaos Rangos has discovered a vulnerability in MySQL, which can be
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to a format string error within the
"dispatch_command()" function in sql_parse.cc. This can be exploited
to crash an affected service via specially crafted "COM_CREATE_DB" or
"COM_DROP_DB" requests.

Successful exploitation requires create database or drop database
privileges.

The vulnerability is confirmed in version 5.0.83 for Windows. Other
versions may also be affected.

SOLUTION:
Update to version 5.1.36, which disables support for the vulnerable
requests.

Grant create database and drop database privileges to trusted users
only.

PROVIDED AND/OR DISCOVERED BY:
Nikolaos Rangos (Kingcope)
