Important release for Debian's krb5 software tackling vulnerabilities related to remote code exploitation and service disruption risks.
Daniel Wachdorf reported two problems in the MIT krb5 distribution used for network authentication.

Summary


All of these vulnerabilities are believed difficult to exploit, and no
exploits have yet been discovered.

For the old stable distribution (woody), these problems have been fixed
in version 1.2.4-5woody10. Note that woody's KDC does not have TCP
support and is not vulnerable to CAN-2005-1174.

For the stable distribution (sarge), these problems have been fixed in
version 1.3.6-2sarge2.

For the unstable distribution (sid), these problems have been fixed in
version 1.3.6-4.

We recommend that you upgrade your krb5 package.
