RHEL 6 : mod_auth_mysql (RHSA-2010:1002)
High Nessus Plugin ID 51357
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionAn updated mod_auth_mysql package that fixes one security issue is now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
The mod_auth_mysql package includes an extension module for the Apache HTTP Server, which can be used to implement web user authentication against a MySQL database.
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.
All mod_auth_mysql users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
After installing the updated package, the httpd daemon must be restarted for the update to take effect.
SolutionUpdate the affected mod_auth_mysql and / or mod_auth_mysql-debuginfo packages.
