"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.

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-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 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."
