Security Fix(es):

- 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)
