Description

According to its self-reported version number, the remote Junos router has a denial of service vulnerability. Receiving an ICMPv6 packet with a corrupted payload within an IPv6 L3VPN can result in a kernel panic. Only VPNv6 configurations without the 'vrf-table-label' statement in the routing instance configuration are affected. A remote, unauthenticated attacker could exploit this to crash the router.
