editLogstash response to Apache Log4j2 vulnerability
editA high severity vulnerability (CVE-2021-44228) impacting multiple versions of the Apache Log4j2 utility was disclosed publicly through the project’s GitHub on December 9, 2021. The vulnerability impacts Apache Log4j2 versions 2.0 to 2.14.1.
In Logstash, we responded by bumping the log4j version to 2.15.0 in #13496 to bypass the vulnerability.
Update to Logstash version 6.8.21 or 7.16.1 to get this fix.
See our related security announcement for additional information.
Known issue
editRelease 7.16.1 includes filter versions that will not run on JDK 8. This issue is fixed in the latest versions:
You can update these plugins as usual:
bin/logstash-plugin update logstash-filter-date bin/logstash-plugin update logstash-filter-geoip
Clear the JAVA_HOME
and LS_JAVA_HOME
environment variables to run Logstash with the bundled JDK (currently JDK 11).
This approach is recommended and can help you avoid version incompatibilities.
Performance improvements and notable issues fixed
edit-
