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)
