Debian Security Advisory DSA 180-1 security@debian.org

Package : nis
Vulnerability : information leak
Problem-Type : remote
Debian-specific: no
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.
