Detail

Several remote vulnerabilities have been discovered in the kdc component of the krb5, a system for authenticating users and services on a network.

CVE-2008-0062

An unauthenticated remote attacker may cause a krb4-enabled KDC to crash, expose information, or execute arbitrary code. Successful exploitation of this vulnerability could compromise the Kerberos key database and host security on the KDC host.

CVE-2008-0063

An unauthenticated remote attacker may cause a krb4-enabled KDC to expose information. It is theoretically possible for the exposed information to include secret key data on some platforms.

CVE-2008-0947

An unauthenticated remote attacker can cause memory corruption in the kadmind process, which is likely to cause kadmind to crash, resulting in a denial of service. It is at least theoretically possible for such corruption to result in database corruption or arbitrary code execution, though we have no such exploit and are not aware of any such exploits in use in the wild. In versions of MIT Kerberos shipped by Debian, this bug can only be triggered in configurations that allow large numbers of open file descriptors in a process.

For the stable distribution (etch), these problems have been fixed in version 1.4.4-7etch5.

For the old stable distribution (sarge), these problems have been fixed in version krb5 1.3.6-2sarge6.

We recommend that you upgrade your krb5 packages.
