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.
