I found no evidence that CVE-2018-8037 is fixed in tomcat 7.0.87.
Comment 8 Timothy Walsh 2018-08-20 06:26:29 EDT 
Review of JWS 3.1 indicates that versions of Tomcat used in that release are not affected.
Comment 9 Timothy Walsh 2018-08-20 06:36:32 EDT 
Red Hat Enterprise Linux 7 supports Tomcat 7 (7.0.76) which is not affected by this flaw.
