DSA 180-1-New NIS packages fix information leak

by Nikola Strahija on October 21st, 2002 Thorsten Kukuck discovered a problem in the ypserv program which is part of the Network Information Services (NIS). A memory leak in all versions of ypserv prior to 2.5 is remotely exploitable. When a malicious user could request a non-existing map the server will leak parts of an old domainname and mapname.

This problem has been fixed in version 3.9-6.1 for the current stable
distribution (woody), in version 3.8-2.1 for the old stable
distribution (potato) and in version 3.9-6.2 for the unstable
distribution (sid).

We recommend that you upgrade your nis package.

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.
