Red Hat Security Advisory

 

Synopsis: Moderate: mod_auth_mysql security update

Advisory ID: RHSA-2009:0259-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0259.html

Issue date: 2009-02-11

CVE Names: CVE-2008-2384

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

 

3. 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.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.
