Descriptions

Receipt of a specifically malformed IPv6 packet processed by the router may trigger a line card reset: processor exception 0x68616c74 (halt) in task: scheduler. The line card will reboot and recover without user interaction. However, additional specifically malformed packets may cause follow-on line card resets and lead to an extended service outage. This issue only affects E Series routers with IPv6 licensed and enabled. Routers not configured to process IPv6 traffic are unaffected by this vulnerability. Juniper SIRT is not aware of any malicious exploitation of this vulnerability. No other Juniper Networks products or platforms are affected by this issue.

La recepción de un paquete IPv6 especialmente mal formado y procesado por el router podría provocar que una tarjeta de línea se reinicie: processor exception 0x68616c74 (halt) in task: scheduler. La tarjeta de red se reiniciar y recupera sin la interacción del usuario. Sin embargo, los paquetes específicamente mal formados adicionales podrían causar reinicios continuados de la tarjeta de línea y causar que el servicio no esté disponible por un periodo extendido de tiempo. Este problema solo afecta a los routers de la serie E con IPv6 en licencia y activado. Los routers no configurados para procesar tráfico IPv6 no se ven afectados por esta vulnerabilidad. Juniper SIRT no conoce ninguna explotación maliciosa de esta vulnerabilidad. No hay ningún otro producto o plataforma de Juniper Networks que se vea afectado por este problema.
