Fedora 14 : mod_auth_mysql-3.0.0-12.fc14 (2011-0100)

Description

This update fixes a security issue in mod_auth_mysql.

A flaw was found in the way mod_auth_mysql escaped certain multibyte-encoded strings. If mod_auth_mysql was configured to use a multibyte character set that allowed a backslash ('\') as part of the character encodings, a remote attacker could inject arbitrary SQL commands into a login request. (CVE-2008-2384)

Note: This flaw only affected non-default installations where AuthMySQLCharacterSet is configured to use one of the affected multibyte character sets. Installations that did not use the AuthMySQLCharacterSet configuration option were not vulnerable to this flaw.

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.
