NVD Description

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

A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds up in the server memory, saturating the server’s RAM. This flaw allows an attacker to force the invocation of an out-of-memory process, causing a denial of service.
