medium Nessus Plugin ID 58875

Language:

Synopsis

The remote router has a denial of service vulnerability.

Description

According to its self-reported version number, the version of Junos running on the remote host has a denial of service vulnerability.
When MPLS is enabled, receiving a high rate of Pseudo Wire (l2vpn or l2circuit) control words from an adjacent node can cause the routing engine (RE) to become overloaded. This could result in an RE switchover, or a reboot in single RE environments.

Solution

Apply the relevant Junos upgrade referenced in Juniper advisory PSN-2012-04-546.
