David Coffey discovered an uninitialized pointer free flaw in the RPC
library used by kadmind. A remote unauthenticated attacker who can access
kadmind could trigger this flaw and cause kadmind to crash or potentially
execute arbitrary code as root. (CVE-2007-2442)

David Coffey also discovered an overflow flaw in the RPC library used by
kadmind. On Scientific Linux, exploitation of this flaw is limited
to a denial of service. A remote unauthenticated attacker who can access
kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-2443)

A stack buffer overflow flaw was found in kadmind. An authenticated
