- ---------------------------------------------------------------------

1. Summary:

An updated nfs-utils-lib package to correct a security flaw is now
available for Red Hat Enterprise Linux 4.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

The nfs-utils-lib package contains support libraries that are needed by the
commands and daemons of the nfs-utils package.

Tenable Network Security discovered a stack buffer overflow flaw in the RPC
library used by nfs-utils-lib. A remote unauthenticated attacker who can
access an application linked against nfs-utils-lib could trigger this flaw
and cause the application to crash. On Red Hat Enterprise Linux 4 it is not
possible to exploit this flaw to run arbitrary code as the overflow is
blocked by FORTIFY_SOURCE. (CVE-2007-3999)

Users of nfs-utils-lib are advised to upgrade to this updated package,
which contains a backported patch that resolves this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

250973 - CVE-2007-3999 krb5 RPC library buffer overflow
