Descriptions

Receipt of a specially crafted DHCPv6 message destined to a Junos OS device configured as a DHCP server in a Broadband Edge (BBE) environment may result in a jdhcpd daemon crash. The daemon automatically restarts without intervention, but a continuous receipt of crafted DHCPv6 packets could leaded to an extended denial of service condition. This issue only affects Junos OS 15.1 and later. Earlier releases are unaffected by this issue. Devices are only vulnerable to the specially crafted DHCPv6 message if DHCP services are configured. Devices not configured to act as a DHCP server are not vulnerable to this issue. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D160; 15.1X53 versions prior to 15.1X53-D235, 15.1X53-D495; 16.1 versions prior to 16.1R4-S11, 16.1R6-S6, 16.1R7-S2; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S9; 17.2 versions prior to 17.2R2-S6; 17.3 versions prior to 17.3R3-S1; 17.4 versions prior to 17.4R1-S5; 18.1 versions prior to 18.1R2-S3; 18.2 versions prior to 18.2R1-S2; 18.2X75 versions prior to 18.2X75-D20.

La recepción de un mensaje DHCPv6 especialmente manipulado destinado a un dispositivo Junos OS configurado como servidor DHCP en un entorno BBE (Broadband Edge) puede resultar en un cierre inesperado del demonio jdhcpd. El demonio se reinicia automáticamente sin intervención, pero la recepción continuada de paquetes DHCPv6 manipulados podría conducir a una condición de denegación de servicio (DoS) prolongada. Este problema solo afecta a Junos OS 15.1 y posteriores. Las versiones anteriores no se han visto afectadas por este problema. Los dispositivos solo son vulnerables al mensaje DHCPv6 especialmente manipulado si los servicios DHCP están configurados. Los dispositivos que no están configurados para actuar como servidor DHCP no son vulnerables a este problema. Las versiones afectadas de Juniper Networks Junos OS son: 15.1 en versiones anteriores a la 15.1R7-S2; 15.1X49 en versiones anteriores a la 15.1X49-D160; 15.1X53 en versiones anteriores a la 15.1X53-D235, 15.1X53-D495; 16.1 en versiones anteriores a la 16.1R4-S11, 16.1R6-S6, 16.1R7-S2; 16.2 en versiones anteriores a la 16.2R2-S7; 17.1 en versiones anteriores a la 17.1R2-S9; 17.2 en versiones anteriores a la 17.2R2-S6; 17.3 en versiones anteriores a la 17.3R3-S1; 17.4 en versiones anteriores a la 17.4R1-S5; 18.1 en versiones anteriores a la 18.1R2-S3; 18.2 en versiones anteriores a la 18.2R1-S2 y 18.2X75 en versiones anteriores a la 18.2X75-D20.
