Description

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).
