RHSA-2009:0259 - Moderate: mod_auth_mysql security update


Synopsis

Moderate: mod_auth_mysql security update

Type/Severity

Security Advisory Moderate

Topic

An updated mod_auth_mysql package to correct a security issue is 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.

Description

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 the updated package, which contains a backported patch to resolve this issue. After installing the update, the httpd daemon must be restarted for the fix to take effect.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
