Description Pedro Sampaio 2018-07-23 15:29:47 EDT 
Flaw affecting tomcat 8.0.0.RC1 to 8.0.51 and 9.0.0.M1 to 9.0.7. An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service.

Comment 9 Chess Hazlett 2018-08-17 15:28:45 EDT 
Statement:

Fuse 6.3 and 7 standalone distributions ship but do not use tomcat, and as such are not affected by this flaw; however, Fuse Integration Services 2.0 and Fuse 7 on OpenShift provide the affected artifacts via their respective maven repositories, and will provide fixes for this issue in a future release.
