SSL: Apache Tomcat NIO Connector Denial of Service
This signature detects attempts to exploit a known flaw in Apache Tomcat. The vulnerability is due to an infinite loop in NIO Connector when a client breaks the connection in the middle of reading the response for a request to a big file. An unauthenticated, remote attacker can exploit this vulnerability by sending HTTP requests for a large file and disconnecting from the server while reading the file. Successful exploitation could result in a denial of service condition.
Extended Description
org/apache/tomcat/util/net/NioEndpoint.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, when the NIO connector is used in conjunction with sendfile and HTTPS, allows remote attackers to cause a denial of service (infinite loop) by terminating the connection during the reading of a response.
