Description

The jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

With this update, the jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 6.4.19.

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)

The CVE-2017-12174 issue was discovered by Masafumi Miura (Red Hat).
