CAN-2004-0642 [VU#795632] A double-free error may allow unauthenticated remote attackers to execute arbitrary code on KDC or clients. CAN-2004-0643 [VU#866472] Several double-free errors may allow authenticated attackers to execute arbitrary code on Kerberos application servers. CAN-2004-0644 [VU#550464] A remotely exploitable denial of service vulnerability has been found in the KDC and libraries. CAN-2004-0772 [VU#350792] Several double-free errors may allow remote attackers to execute arbitrary code on the server. This does not affect the version in woody.

For the stable distribution (woody) these problems have been fixed in version 1.2.4-5woody6.

For the unstable distribution (sid) these problems have been fixed in version 1.3.4-3.

We recommend that you upgrade your krb5 packages.");
