Detail

Problem Description:

An updated auth_ldap packages that fixes a format string security issue is now available for Red Hat Enterprise Linux 2.1.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

3. Problem description:

The auth_ldap package is an httpd module that allows user authentication against information stored in an LDAP database.

A format string flaw was found in the way auth_ldap logs information. It may be possible for a remote attacker to execute arbitrary code as the 'apache' user if auth_ldap is used for user authentication. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0150 to this issue.

Note that this issue only affects servers that have auth_ldap installed and configured to perform user authentication against an LDAP database.

All users of auth_ldap should upgrade to this updated package, which contains a backported patch to resolve this issue.

This issue does not affect the Red Hat Enterprise Linux 3 or 4 distributions as they do not include the auth_ldap package.

This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
