Descriptions
ntp_crypto.c in ntpd in NTP 4.x before 4.2.8p1, when Autokey Authentication is enabled, allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a packet containing an extension field with an invalid value for the length of its value field.
ntp_crypto.c en ntpd en NTP 4.x en versiones anteriores a 4.2.8p1, cuando Autokey Authentication está habilitada, permite a atacantes remotos obtener información sensible de la memoria de proceso o causar una denegación de servicio (caída del demonio) a través de un paquete que contiene un campo extension con un valor no válido para la longitud de su campo de valor.
A stack-based buffer overflow was found in the way the NTP autokey protocol was implemented. When an NTP client decrypted a secret received from an NTP server, it could cause that client to crash.
