Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to a new upstream version, 5.1.66, which includes additional changes, such as performance improvements and corrections for data loss defects. These changes are described in the MySQL release notes.

For the testing distribution (wheezy) and unstable distribution (sid), these problems have been fixed in version 5.5.28+dfsg-1. Additionally, CVE-2012-5611 has been fixed in this upload. The vulnerability (discovered independently by Tomas Hoger from the Red Hat Security Response Team and king cope) is a stack-based buffer overflow in acl_get() when checking user access to a database. Using a carefully crafted database name, an already authenticated MySQL user could make the server crash or even execute arbitrary code as the mysql system user. For the stable distribution (squeeze), this problem has been fixed in version 5.1.66-0+squeeze1. For the testing distribution (wheezy) and unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your mysql-5.1 packages.

MySQL is a fast, stable and true multi-user, multi-threaded SQL database server.
