MySQL 5.1.x before 5.1.63 and 5.5.x before 5.5.24 allows remote authenticated users to cause a denial of service (mysqld crash) via vectors related to incorrect calculation and a sort order index.

The remote host is affected by the vulnerability described in GLSA-201308-06 (MySQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MySQL. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could send a specially crafted request, possibly       resulting in execution of arbitrary code with the privileges of the       application or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

From Red Hat Security Advisory 2013:0180 :

Updated mysql packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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 stack-based buffer overflow flaw was found in the user permission checking code in MySQL. An authenticated database user could use this flaw to crash the mysqld daemon or, potentially, execute arbitrary code with the privileges of the user running the mysqld daemon.
(CVE-2012-5611)

A flaw was found in the way MySQL calculated the key length when creating a sort order index for certain queries. An authenticated database user could use this flaw to crash the mysqld daemon.
(CVE-2012-2749)

This update also adds a patch for a potential flaw in the MySQL password checking function, which could allow an attacker to log into any MySQL account without knowing the correct password. This problem (CVE-2012-2122) only affected MySQL packages that use a certain compiler and C library optimization. It did not affect the mysql packages in Red Hat Enterprise Linux 5. The patch is being added as a preventive measure to ensure this problem cannot get exposed in future revisions of the mysql packages. (BZ#814605)

All MySQL users should upgrade to these updated packages, which correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

The version of MySQL 5.5 installed on the remote host is earlier than 5.5.24 and is, therefore, affected by the following vulnerabilities :

  - Several errors exist related to 'GIS Extension',  'Server', 'InnoDB' and 'Server Optimizer' components that can allow denial of service attacks. (CVE-2012-0540, CVE-2012-1734, CVE-2012-1735, CVE-2012-1756, CVE-2012-1757)

  - A security bypass vulnerability exists that occurs due to improper casting during user login sessions. (Bug #64884 / CVE-2012-2122)

  - An error exists related to key length and sort order  index that can lead to application crashes. (Bug #59387 / CVE-2012-2749)

The version of MySQL 5.1 installed on the remote host is earlier than 5.1.63 and is, therefore, affected by the following vulnerabilities :

  - Several errors exist related to 'GIS Extension' and 'Server Optimizer' components that can allow denial of service attacks. (CVE-2012-0540, CVE-2012-1689, CVE-2012-1734)

  - A security bypass vulnerability exists that occurs due to improper casting during user login sessions. (Bug #64884 / CVE-2012-2122)

  - An error exists related to key length and sort order  index that can lead to application crashes. (Bug #59387 / CVE-2012-2749

Due to the non-disclosure of security patch information from     Oracle, we are forced to ship an upstream version update of MySQL     5.1. There are several known incompatible changes, which are     listed in /usr/share/doc/mysql-server/NEWS.Debian.gz.

Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to a new upstream version, 5.1.63, which includes additional changes, such as performance improvements and corrections for data loss defects. These changes are described in the MySQL release notes.

 CVE-2012-2122, an authentication bypass vulnerability, occurs only  when MySQL has been built in with certain optimisations enabled. The  packages in Debian stable (squeeze) are not known to be affected by  this vulnerability. It is addressed in this update nonetheless, so  future rebuilds will not become vulnerable to this issue.

The version of MySQL 5.5 installed on the remote host is earlier than 5.5.24 and is, therefore, affected by the following vulnerabilities :

  - Several errors exist related to 'GIS Extension',     'Server', 'InnoDB' and 'Server Optimizer' components     that can allow denial of service attacks.
    (CVE-2012-0540, CVE-2012-1734, CVE-2012-1735,     CVE-2012-1756, CVE-2012-1757)

  - A security bypass vulnerability exists that occurs due     to improper casting during user login sessions.
    (Bug #64884 / CVE-2012-2122)

  - An error exists related to key length and sort order     index that can lead to application crashes.
    (Bug #59387 / CVE-2012-2749)

The version of MySQL 5.1 installed on the remote host is earlier than 5.1.63 and is, therefore, affected by multiple vulnerabilities :

  - Several errors exist related to 'GIS Extension' and     'Server Optimizer' components that can allow denial of     service attacks. (CVE-2012-0540, CVE-2012-1689,     CVE-2012-1734)

  - A security bypass vulnerability exists that occurs due     to improper casting during user login sessions.
