Red Hat Security Advisory 2012-0874-04
Posted Jun 20, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0874-04 - MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon 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.

3. Description:

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:

* The InnoDB storage engine is built-in for all architectures. This update
adds InnoDB Plugin, the InnoDB storage engine as a plug-in for the 32-bit
x86, AMD64, and Intel 64 architectures. The plug-in offers additional
features and better performance than when using the built-in InnoDB storage
engine. Refer to the MySQL documentation, linked to in the References
section, for information about enabling the plug-in. (BZ#740224)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

740224 - Enabling MySQL InnoDB Plugin
812431 - CVE-2012-2102 mysql: Server crash on HANDLER READ NEXT after DELETE
