The Apache Software Foundation on Tuesday rolled out fresh patches to contain an arbitrary code execution flaw in Log4j that could be abused by threat actors to run malicious code on affected systems, making it the fifth security shortcoming to be discovered in the tool in the span of a month.

With the latest fix, the project maintainers have addressed a total of four issues in Log4j since the Log4Shell flaw came to light earlier this month, not to mention a fifth vulnerability affecting versions Log4j 1.2 that will not be fixed -.
CVE-2021-44228 - A remote code execution vulnerability affecting Log4j versions from 2.0-beta9 to 2.14.1.
CVE-2021-45046 - An information leak and remote code execution vulnerability affecting Log4j versions from 2.0-beta9 to 2.15.0, excluding 2.12.2.
CVE-2021-45105 - A denial-of-service vulnerability affecting Log4j versions from 2.0-beta9 to 2.16.0.
