Juniper Junos VPLS Ethernet Frame MAC Address Remote DoS (JSA10750)

Medium Nessus Plugin ID 92518

Synopsis

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

Description

According to its self-reported version number and configuration, the remote Juniper Junos device is affected by a denial of service vulnerability when VPLS routing-instances are configured. An unauthenticated, adjacent attacker can exploit this, via Ethernet frames with the EtherType field of IPv6 (0x86DD), to cause a denial of service condition.

Solution

Upgrade to the relevant Junos software release referenced in Juniper advisory JSA10750. Alternatively, if EtherType IPv6 MAC addresses are not required, configure a VPLS flood filter.
