Multiple vulnerabilities were discovered and corrected in mysql:

* Joins involving a table with with a unique SET column could cause
a server crash (CVE-2010-3677).

* Use of TEMPORARY InnoDB tables with nullable columns could cause
a server crash (CVE-2010-3680).

* The server could crash if there were alternate reads from two
indexes on a table using the HANDLER interface (CVE-2010-3681).

* Using EXPLAIN with queries of the form SELECT ... UNION ... ORDER BY
(SELECT ... WHERE ...) could cause a server crash (CVE-2010-3682).

* During evaluation of arguments to extreme-value functions (such
as LEAST() and GREATEST()), type errors did not propagate properly,
causing the server to crash (CVE-2010-3833).

* The server could crash after materializing a derived table that
required a temporary table for grouping (CVE-2010-3834).

* A user-variable assignment expression that is evaluated in a logical
expression context can be precalculated in a temporary table for GROUP
BY. However, when the expression value is used after creation of the
temporary table, it was re-evaluated, not read from the table and a
server crash resulted (CVE-2010-3835).

* Pre-evaluation of LIKE predicates during view preparation could
cause a server crash (CVE-2010-3836).

* GROUP_CONCAT() and WITH ROLLUP together could cause a server crash
(CVE-2010-3837).

* Queries could cause a server crash if the GREATEST() or LEAST()
function had a mixed list of numeric and LONGBLOB arguments, and
the result of such a function was processed using an intermediate
temporary table (CVE-2010-3838).

* Queries with nested joins could cause an infinite loop in the
server when used from stored procedures and prepared statements
(CVE-2010-3839).

* The PolyFromWKB() function could crash the server when improper
WKB data was passed to the function (CVE-2010-3840).

Additionally the default behaviour of using the mysqlmanager instead
of the mysqld_safe script has been reverted in the SysV init script
because of instability issues with the mysqlmanager.

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:

The updated packages have been upgraded to mysql 5.0.91 and patched
to correct these issues.
