NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-admin-webapps package and not the tomcat-admin-webapps package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 processes chunked transfer coding without properly handling (1) a large total amount of chunked data or (2) whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial of service by streaming data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3544.
