Summary

A programming error in the processing of HTTPS requests in the Apache Tomcat servlet and JSP engine can lead to a denial of service condition. This vulnerability stems from a failure to backport a crucial fix during a previous patch implementation, resulting in an infinite loop which can easily be exploited. Affected versions include certain Debian distributions prior to 7.0.56-3+deb8u8 and 8.0.14-1+deb8u7, as well as various Ubuntu versions. Organizations using these distributions are advised to update their systems to mitigate the risk.
