New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated mysql packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.
MySQL did not correctly check directories used as arguments for the DATA DIRECTORY and INDEX DIRECTORY directives. Using this flaw, an authenticated attacker could elevate their access privileges to tables created by other database users. Note: This attack does not work on existing tables. An attacker can only elevate their access to another user's tables as the tables are created. As well, the names of these created tables need to be predicted correctly for this attack to succeed. (CVE-2008-2079)
A flaw was found in the way MySQL handles an empty bit-string literal.
A remote, authenticated attacker could crash the MySQL server daemon (mysqld) if they used an empty bit-string literal in a SQL statement.
This issue only caused a temporary denial of service, as the MySQL daemon was automatically restarted after the crash. (CVE-2008-3963)
An insufficient HTML entities quoting flaw was found in the mysql command line client's HTML output mode. If an attacker was able to inject arbitrary HTML tags into data stored in a MySQL database, which was later retrieved using the mysql command line client and its HTML output mode, they could perform a cross-site scripting (XSS) attack against victims viewing the HTML output in a web browser.
Multiple format string flaws were found in the way the MySQL server logs user commands when creating and deleting databases. A remote, authenticated attacker with permissions to CREATE and DROP databases could use these flaws to formulate a specifically-crafted SQL command that would cause a temporary denial of service (open connections to mysqld are terminated). (CVE-2009-2446)
Note: To exploit the CVE-2009-2446 flaws, the general query log (the mysqld '--log' command line option or the 'log' option in '/etc/my.cnf') must be enabled. This logging is not enabled by default.
This update also fixes multiple bugs. Details regarding these bugs can be found in the Red Hat Enterprise Linux 5.4 Technical Notes. You can find a link to the Technical Notes in the References section of this errata.
Note: These updated packages upgrade MySQL to version 5.0.77 to incorporate numerous upstream bug fixes. Details of these changes are found in the following MySQL Release Notes:
All MySQL users are advised to upgrade to these updated packages, which resolve these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
SolutionUpdate the affected mysql packages.
