🎯 Affected products1
- Red Hat JBoss Enterprise Application Platform 5.2 security update
✅ Remediation
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications. The References section of this erratum contains a download link (you must log in to download the update). Workaround: Please note that the Log4j upstream strongly recommends against using the SerializedLayout with the SocketAppenders. Customers may mitigate this issue by removing the SocketServer class outright; or if they must continue to use SocketAppenders, they can modify their SocketAppender configuration from SerializedLayout to use JsonLayout instead. An example of this in log4j-server.properties might look like this: log4j.appender.file.layout=org.apache.log4j.JsonLayout
