"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.

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."
