DESCRIPTION
 The nfs-utils[1] package provides the utilities for Linux NFS client
 and server.
 
 Janusz Niewiadomski found[2] a buffer overflow vulnerability[3] in
 the nfs-utils package that could be used by remote attackers to cause
 a denial of service condition or execute arbitrary code with
 administrator privileges.
 
 To fix this issue, the author has released[4] a new version. The
 packages made available through this update contain the same fix as
 the one applied to this new version, 1.0.4.


SOLUTION
 It is recommended that all nfs-utils users upgrade their packages.
 
 IMPORTANT: after the upgrade, the nfs and nfs-lock services have to
 be restarted if they were already running. To do this, run the
 following commands as root:
 
 /sbin/service nfs restart
 /sbin/service nfslock restart
