Description

This security bulletin contains information about 1 security vulnerability.


1) Missing release of memory after effective lifetime (CVE-ID: CVE-2024-21611)

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 Routing Protocol Daemon (rpd). A remote non-authenticated attacker can cause a Denial of Service (DoS).

In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd.
