## Description

Buffer overflow in the RPC library (lib/rpc/rpc\_dtablesize.c) used by
libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other
versions before 1.3, when running on systems whose unistd.h does not define
the FD\_SETSIZE macro, allows remote attackers to cause a denial of service
(crash) and possibly execute arbitrary code by triggering a large number of
open file descriptors.
