MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.
A flaw was found in the way MySQL processed HANDLER READ NEXT statements after deleting a record. A remote, authenticated attacker could use this flaw to provide such requests, causing mysqld to crash. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2012-2102)
This update also adds the following enhancement:
All MySQL users should upgrade to these updated packages, which add this enhancement and contain a backported patch to correct this issue. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
