Fedora 34: log4j 2021-66d6c484f3
Summary
Log4j is a tool to help the programmer output log statements to a
variety of output targets.
This update provides log4j 2.16.0, to address the critical vulnerability
CVE-2021-44228 ("Log4Shell"). Note with 2.16.0, JNDI is entirely disabled by
default; to use it, you must set `log4j2.enableJndi` (please carefully consider
potential security issues before doing so). The updated jansi adds (back) a
feature, `AnsiRenderer`, which the newer log4j requires; this is the only change
to jansi. For other changes in log4j 2.16.0, see the [upstream
changelog]().
Most changes are compatible enhancements or bug fixes, but there may be some
behaviour changes.
