Description Guilherme de Almeida Suckevicz 2019-12-30 16:41:41 UTC
ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a use after free. A remote unauthenticated attacker can crash the ELOG server by sending multiple HTTP POST requests which causes the ELOG function retrieve_url() to use a freed variable.
