"An updated nfs-utils-lib package to correct two security flaws is now
available for Red Hat Enterprise Linux 5.

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

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

The updated nfs-utils package fixes the following vulnerabilities :

Tenable Network Security discovered a stack-based 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 5 it is not possible to exploit this flaw to run
arbitrary code as the overflow is blocked by FORTIFY_SOURCE.
(CVE-2007-3999)

Tony Ernst from SGI has discovered a flaw in the way nfsidmap maps
NFSv4 unknown uids. If an unknown user ID is encountered on an NFSv4
mounted filesystem, the files will default to being owned by 'root'
rather than 'nobody'. (CVE-2007-4135)

Users of nfs-utils-lib are advised to upgrade to this updated package,
which contains backported patches to resolve these issues."
