Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 Scientific 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.

After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

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.

Update to MySQL 5.5.24, for various fixes described at http://dev.mysql.com/doc/refman/5.5/en/news-5-5-24.html including the fix for CVE-2012-2122

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)

MySQL has been upgraded to version 5.0.96 to fix several vulnerabilities.

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - sql/password.c in Oracle MySQL 5.1.x before 5.1.63, 5.5.x before 5.5.24, and 5.6.x before 5.6.6, and     MariaDB 5.1.x before 5.1.62, 5.2.x before 5.2.12, 5.3.x before 5.3.6, and 5.5.x before 5.5.23, when     running in certain environments with certain implementations of the memcmp function, allows remote     attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which     eventually causes a token comparison to succeed due to an improperly-checked return value. (CVE-2012-2122)

Note that Nessus relies on the presence of the package as reported by the vendor.

This version upgrade of mysql-cluster to version 7.1.22 fixed an authentication bypass flaw. Additionally, this version upgrade also includes fixes for various other bugs.

It was discovered that certain builds of MySQL incorrectly handled password authentication on certain platforms. A remote attacker could use this issue to authenticate with an arbitrary password and establish a connection. (CVE-2012-2122)

MySQL has been updated to 5.5.24 in Ubuntu 12.04 LTS. Ubuntu 10.04 LTS, Ubuntu 11.04 and Ubuntu 11.10 have been updated to MySQL 5.1.63.
A patch to fix the issue was backported to the version of MySQL in Ubuntu 8.04 LTS.

In addition to additional security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Please see the following for more information :

http://dev.mysql.com/doc/refman/5.5/en/news-5-5-24.html http://dev.mysql.com/doc/refman/5.1/en/news-5-1-63.html

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A flaw in the MySQL server allows remote users to authenticate without a valid password due to a failure when casting a randomly generated token and comparing it to an expected value.

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.
    (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)
