Summary

Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on WildFly.
This asynchronous patch is a security update for slf4j package in Red Hat JBoss Enterprise Application Platform 7.1.
Security Fix(es):
* An XML deserialization vulnerability was discovered in slf4j's EventData which accepts xml serialized string and can lead to arbitrary code execution. (CVE-2018-8088)
The Simple Logging Facade for Java or (SLF4J) is a simple facade for various logging APIs allowing the end-user to plug in the desired implementation at deployment time. SLF4J also allows for a gradual migration path away from Jakarta Commons Logging (JCL).
Red Hat would like to thank Chris McCown for reporting CVE-2018-8088.
