NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat7 package and not the tomcat7 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

It was discovered that a programming error in the processing of HTTPS requests in the Apache Tomcat servlet and JSP engine may result in denial of service via an infinite loop. The denial of service is easily achievable as a consequence of backporting a CVE-2016-6816 fix but not backporting the fix for Tomcat bug 57544. Distributions affected by this backporting issue include Debian (before 7.0.56-3+deb8u8 and 8.0.14-1+deb8u7 in jessie) and Ubuntu.
