Descriptions

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.

Un desbordamiento de búfer en la biblioteca RPC (lib/rpc/rpc_dtablesize.c) utilizada por libgssrpc y kadmind en MIT Kerberos 5 (krb5) versión 1.2.2, y probablemente otras versiones anteriores a 1.3, cuando se ejecuta en sistemas cuyo unistd.h no define la macro FD_SETSIZE, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario mediante la activación de un gran número de descriptores de archivos abiertos.
