Description

This security bulletin contains information about 1 security vulnerability.


1) Missing release of memory after effective lifetime (CVE-ID: CVE-2024-47493)

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

The vulnerability exists due to missing release of memory after effective lifetime error in the Packet Forwarding Engine (PFE). A remote non-authenticated attacker can cause a Denial of Service (DoS).

In case of channelized Modular Interface Cards (MICs), every physical interface flap operation will leak heap memory.

Over a period of time, continuous physical interface flap operations causes local FPC to eventually run out of memory and crash.
