    Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0179.html
    Issue date: 2006-01-10
    Updated on: 2006-01-10
    Product: Red Hat Enterprise Linux
    CVE Names: CVE-2006-0150
    - ---------------------------------------------------------------------
    
    1. Summary:
    
    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:
    
    Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
    Red Hat Linux Advanced Workstation 2.1 - ia64
    Red Hat Enterprise Linux ES version 2.1 - i386
    Red Hat Enterprise Linux WS version 2.1 - i386
    
    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.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via Red Hat Network. To use Red Hat Network,
    launch the Red Hat Update Agent with the following command:
    
    up2date
    
    This will start an interactive process that will result in the appropriate
    RPMs being upgraded on your system.
