A stack buffer overflow in the kadm_ser_wrap_in function in the Kerberos v4 administration server was discovered, which is provided by Heimdal as well. A working exploit for this kadmind bug is already circulating, hence it is considered serious. The roken library also contains a vulnerability which could lead to another root exploit.
These problems have been fixed in version 0.4e-7.woody.5 for the current stable distribution (woody), in version 0.2l-7.6 for the old stable distribution (potato) and in version 0.4e-22 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
