Junos OS: NG-mVPN rpd DoS (JSA10965)

Medium Nessus Plugin ID 130504

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 an unexpected status return value weakness in the Next-Generation Multicast VPN (NG-mVPN) which can result in a denial of service (DoS) condition. An unauthenticated, remote attacker can exploit this issue, by repeatedly sending crafted, malformed IPv4 packets to a victim device, including when these packets are forwarded directly through a device, provided that the malformed packet is not first de-encapsulated from an encapsulated format by a receiving device. This allows an attacker to cause the system to stop responding.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA10965.
