DESCRIPTION:
S. Streichbier and B. Mueller have reported 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 NULL-pointer dereference error
within the filesort() function when processing certain single-row
subselect queries sorted using the "ORDER BY" clause. This can be
exploited to crash the service via a specially crafted SQL query.

SOLUTION:
Update to version 5.0.37.
