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.
