Description

Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server.

This asynchronous patch is a security update for log4j package in Red Hat JBoss Enterprise Application Platform 5.2.0.

Security Fix(es):

An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. (CVE-2017-5645)
