Descriptions
Multiple integer overflows in pktlength.c in Chrony before 1.29 allow remote attackers to cause a denial of service (crash) via a crafted (1) REQ_SUBNETS_ACCESSED or (2) REQ_CLIENT_ACCESSES command request to the PKL_CommandLength function or crafted (3) RPY_SUBNETS_ACCESSED, (4) RPY_CLIENT_ACCESSES, (5) RPY_CLIENT_ACCESSES_BY_INDEX, or (6) RPY_MANUAL_LIST command reply to the PKL_ReplyLength function, which triggers an out-of-bounds read or buffer overflow. NOTE: versions 1.27 and 1.28 do not require authentication to exploit.
Múltiples desbordamientos de enteros en pktlength.c en Chrony anterior a 1.29 permite a atacantes remotos provocar una denegación de servicio (caída) a través de un (1) REQ_SUBNETS_ACCESSED manipulado o (2) comando REQ_CLIENT_ACCESSES a la función PKL_CommandLength o la manipulación de (3) RPY_SUBNETS_ACCESSED, (4) RPY_CLIENT_ACCESSES), (5) RPY_CLIENT_ACCESSES_BY_INDEX, o (6) Respuesta del comando RPY_MANUAL_LIST por la función PKL_ReplyLength, lo que provoca un desbordamiento de buffer o lectura fuera de límite.
