PACKAGE : nfs-utils
SUMMARY : Buffer overflow vulnerability
DATE : 2003-07-22 10:17:00
ID : CLA-2003:700
RELEVANT
RELEASES : 7.0, 8, 9

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 ro

/sbin/service nfs restart
/sbin/service nfslock restart
