Security Fix(es):

• It was found that when Artemis and HornetQ are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError. (CVE-2017-12174)

• A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution. (CVE-2017-12617)

• A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10.Final-redhat-1, reads from an empty buffer. An attacker could use this flaw to cause denial of service via high CPU caused by an infinite loop. (CVE-2018-1041)
