"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-based buffer overflow flaw was found in kadmind. An
authenticated attacker who can access kadmind could trigger this flaw
and potentially execute arbitrary code on the Kerberos server.
(CVE-2007-2798)"
