Package        : ntp
Vulnerability  : programming error
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-2496

SuSE developers discovered that ntp confuses the given group id with
the group id of the given user when called with a group id on the
commandline that is specified as a string and not as a numeric gid,
which causes ntpd to run with different privileges than intended.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in
version 4.2.0a+stable-2sarge1.

The unstable distribution (sid) is not affected by this problem.

We recommend that you upgrade your ntp-server package.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
