Juniper Junos IPv6 Egress Filter DoS (PSN-2013-04-915)

high Nessus Plugin ID 66513

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version number, the remote Junos device has a denial of service vulnerability. Specially crafted IPv6 packets that match IPv6 egress filters with a discard or reject action on the lo0 interface can result in a memory leak. This can lead to MBUF exhaustion, resulting in a kernel crash. A remote, unauthenticated attacker could exploit this to crash the host.

Solution

Apply the relevant Junos upgrade referenced in Juniper advisory PSN-2013-04-915.
