This asynchronous patch is a security update for slf4j package in Red Hat JBoss Enterprise Application Platform 6.4.

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)
