✅ Remediation

For OpenShift Container Platform 4.9 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this errata update: https://docs.openshift.com/container-platform/4.9/release_notes/ocp-4-9-release-notes.html For Red Hat OpenShift Logging 5.3, see the following instructions to apply this update: https://docs.openshift.com/container-platform/4.9/logging/cluster-logging-upgrading.html Workaround: For Log4j versions >=2.10 set the system property log4j2.formatMsgNoLookups or the environment variable LOG4J_FORMAT_MSG_NO_LOOKUPS to true For Log4j versions >=2.7 and <=2.14.1 all PatternLayout patterns can be modified to specify the message converter as %m{nolookups} instead of just %m For Log4j versions >=2.0-beta9 and <=2.10.0 remove the JndiLookup class from the classpath. For example: ``` zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class ``` On OpenShift 4 and in OpenShift Logging, the above mitigation can be applied by following the steps in this article: https://access.redhat.com/solutions/6578421 On OpenShift 3.11, mitigation to the affected Elasticsearch component can be applied by following the steps in this article: https://access.redhat.com/solutions/6578441 Workaround: For Log4j versions up to and including 2.15.0, this issue can be mitigated by removing the JndiLookup class from the classpath (example: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class).
