| Doc Text: |
A flaw was found in Apache Tomcat, where an h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests are made, an OutOfMemoryException could occur, leading to a denial of service. The highest threat from this vulnerability is to system availability.

This vulnerability is out of security support scope for the following products: * Red Hat Enterprise Application Platform 6 * Red Hat Data Grid 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details. Red Hat Jboss Fuse 6 ships some of the vulnerable artifacts as bundled artifacts in ops4j pax web, however there is no use of these artifacts in Fuse itself, the artifacts are also prevented from loading with a deny list in karaf, for these reasons we believe the impact upon Fuse 6.3 is low.
