Red Hat Security Advisory: mysql security and enhancement update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:0874 Final 4 4 2012-06-20T08:29:00Z Current version 2012-06-20T08:29:00Z 2012-06-20T08:29:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-06-20T09:05:09Z Updated mysql packages that fix one security issue and add one enhancement are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 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. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2012 Red Hat, Inc.
