Description
This security bulletin contains information about 1 security vulnerability.
1) Missing Synchronization (CVE-ID: CVE-2024-30387)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a missing synchronization error in the Packet Forwarding Engine (PFE). A remote authenticated attacker on the local network can cause a Denial-of-Service (DoS).
If an interface flaps while the system gathers statistics on that interface, two processes simultaneously access a shared resource which leads to a PFE crash and restart.
