CVE-2014-0227: Input Validation

First published: Fri Jun 13 2014(Updated: )

`java/org/apache/coyote/http11/filters/ChunkedInputFilter.java` in Apache Tomcat 6.x before 6.0.42, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle attempts to continue reading data after an error has occurred, which allows remote attackers to conduct HTTP request smuggling attacks or cause a denial of service (resource consumption) by streaming data with malformed chunked transfer coding.
