Description The issue is related to an uncontrolled resource consumption when processing certain MPLS packets, which can be exploited by a remote attacker to cause a denial of service using specially crafted packets. This issue affects devices with VPLS routing-instances configured on one or more interfaces, where an mbuf leak occurs when processing a specific MPLS packet, approximately 1 mbuf per packet. Once the device runs out of mbufs, it will become inaccessible and require a restart. This issue only affects end devices, while transit devices are not affected.
