Junos OS: pd crash on VPLS PE upon receipt of specific BGP message (JSA10912)

high Nessus Plugin ID 121111

Synopsis

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

Description

According to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability which allows an attacker to craft a specific BGP message to cause the routing protocol daemon (rpd) process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition.

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA10912.
