### Motivation - more details at https://logging.apache.org/log4j/2.x/security.html description of CVE-2021-45105 > Apache Log4j2 versions 2.0-alpha1 through 2.16.0 did not protect from uncontrolled recursion from self-referential lookups. When the logging configuration uses a non-default Pattern Layout with a Context Lookup (for example, $${ctx:loginId}), attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup, resulting in a StackOverflowError that will terminate the process. This is also known as a DOS (Denial of Service) attack. - default Pulsar configurations aren't impacted ### Modifications - upgrade Log4J version from 2.16.0 to 2.17.0 -- This is an automated message from the Apache Git Service.
