    22/12/2021 Axel Seedig: Apache has patched Log4j twice more since this article came out. The first update, to 2.16.0, patches against CVE-2021-45046, where a non-default configuration could permit remote code execution or data exfiltration, and a default configuration could allow a denial of service attack causing the affected process to hang. The second update, 2.17.0, patches against CVE-2021-45105, where a non-default configuration could allow an infinite loop, causing a denial of service in a similar way to the flaw patched in 2.16.0.
    Note that patching to 2.17.0 includes all previous fixes, dealing with CVE-2021-44228, CVE-2012-45046 and CVE-2021-45105 at the same time. For ongoing information, please refer to the official About Apache Log4j page. [2021-12-18T11:45:00Z]
