Descriptions

The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of "future epoch" DTLS records that are buffered in a queue, aka "DTLS record buffer limitation bug."

La función dtls1_buffer_record en ssl/d1_pkt.c en OpenSSL 0.9.8k y anteriores permite a atacantes remotos producir una denegación de servicio (consumo de memoria) a través de series largas de registros DTLS de "eras futuras" que se almacenan en búfer en una cola, también conocido como "fallo de limitación de la grabación de búfer DTLS"
