Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of exceptional conditions error in the Routing Protocol Daemon (rpd). A remote non-authenticated attacker can cause Denial of Service (DoS).

When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts.

Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices.
