NVD Description

Note: Versions mentioned in the description apply only to the upstream cockpit package and not the cockpit package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service.
