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.
