Fedora 34 FEDORA-2021-66d6c484f3 Critical: Log4j RCE Patch

Jansi is a small java library that allows you to use ANSI escape sequences

in your Java console applications. It implements ANSI support on platforms

which don't support it like Windows and provides graceful degradation for

when output is being sent to output devices which cannot support ANSI sequences.

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.
