Synopsis

The remote router has a denial of service vulnerability.

Description

According to its self-reported version number, the remote Juniper router has a denial of service vulnerability. In a Next Generation MVPN scenario, a kernel memory buffer could get corrupted when the router receives a bootstrap or auto-RP message larger than 204 bytes, causing the kernel to crash every time a packet is received.

This issue only occurs in Next-Gen MVPN scenarios that use Ingress Replication as the P-tunnel type and has Auto-RP or Bootstrap as the group-to-RP mapping mechanism.
