Scientific Linux Security Update : mysql on SL5.x i386/x86_64
Medium Nessus Plugin ID 63678
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA 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.
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.
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.
SolutionUpdate the affected packages.
