CVE-2019-14810
A vulnerability has been found in the implementation of the Label Distribution Protocol (LDP) protocol in EOS.
Does this matter?
Lower severity and a low EPSS score (0.67%). Track it; it rarely justifies an emergency change on its own.

A vulnerability has been found in the implementation of the Label Distribution Protocol (LDP) protocol in EOS. Under race conditions, the LDP agent can establish an LDP session with a malicious peer potentially allowing the possibility of a Denial of Service (DoS) attack on route updates and in turn potentially leading to an Out of Memory (OOM) condition that is disruptive to traffic forwarding.
