The SuSE Security Team has reviewed critical parts of the Heimdal package such as the kadmind and kdc server. While doing so several potential buffer overflows and other bugs have been uncovered and fixed. Remote attackers can probably gain remote root access on systems without fixes. Since these services usually run on authentication servers these bugs are considered very serious.
These problems have been fixed in version 0.4e-7.woody.4 for the current stable distribution (woody), in version 0.2l-7.4 for the old stable distribution (potato) and version 0.4e-21 for the unstable distribution (sid).
We recommend that you upgrade your Heimdal packages immediately.
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.
Debian GNU/Linux 2.2 alias potato ---------------------------------
Please note that the source packages mentioned above produce more binary packages than the ones listed above. They are not relevant for the fixed problems, though.
These files will probably be moved into the stable distribution on its next revision.
