Descriptions

Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries.

Un desbordamiento del búfer en la función lldp_decode en el archivo daemon/protocolos/lldp.c en lldpd versiones anteriores a 0.8.0, permite a atacantes remotos causar una denegación de servicio (bloqueo de daemon) y posiblemente ejecutar código arbitrario por medio de vectores que involucran grandes direcciones de administración y límites de TLV.
