CVE-2012-4534 is an infinite-loop denial-of-service vulnerability in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28. The NIO connector mishandles sendfile operations when HTTPS is enabled. If a remote client terminates its connection while Tomcat is reading a response, the affected connector can enter an infinite loop.
