Descriptions

A vulnerability in the Network Address Translation - Protocol Translation (NAT-PT) feature of Junos OS on SRX series devices may allow a certain valid IPv6 packet to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition for the SRX device. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D72; 12.3X48 versions prior to 12.3X48-D55; 15.1X49 versions prior to 15.1X49-D90.

Una vulnerabilidad en la característica Network Address Translation - Protocol Translation (NAT-PT) de Junos OS en dispositivos de serie SRX puede permitir que un determinado paquete IPv6 válido cierre inesperadamente el demonio flowd. El cierre inesperado repetido del demonio flowd puede resultar en una condición de denegación de servicio extendida para los dispositivos de la serie SRX. Las versiones afectadas son Juniper Networks Junos OS: 12.1X46 anterior a 12.1X46-D72; 12.3X48 anterior a 12.3X48-D55 y 15.1X49 anterior a 15.1X49-D90.
