CVE-2021-4213 – JSS: memory leak in TLS connection leads to OOM
https://notcve.org/view.php?id=CVE-2021-4213
11 May 2022 — 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. Se ha encontrado un fallo en JSS, que no libera apropiadamente toda la memoria. Con el tiempo, la memoria desperdiciada es acumulada en la memoria del servidor, saturando la RAM del mismo. • https://access.redhat.com/security/cve/CVE-2021-4213 • CWE-401: Missing Release of Memory after Effective Lifetime •
