请求服务报Error parsing HTTP request header

Fixed in Apache Tomcat 7.0.73

Important: Remote Code Execution CVE-2016-8735

The 

JmxRemoteLifecycleListener

 was not updated to take account of Oracle's fix for CVE-2016-3427.
Therefore, Tomcat installations using this listener remained vulnerable to a similar remote code execution vulnerability. This issue has been rated as important rather than critical due to the small number of installations using this listener and that it would
be highly unusual for the JMX ports to be accessible to an attacker even when the listener is used.

This was fixed in revision 1767676.

This issue was reported to the Apache Tomcat Security Team on 19 October 2016 and made public on 22 November 2016.

Affects: 7.0.0 to 7.0.72

Important: Information Disclosure CVE-2016-6816

The code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into
the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.

This was fixed in revision 1767675.

This issue was reported to the Apache Tomcat Security Team on 11 October 2016 and made public on 22 November 2016.

Affects: 7.0.0 to 7.0.72

修复这一BUG是为了防止XSS攻击或者获取敏感数据。

只需要对传输的数据中：一些字符，像{，}，[, ]等等进行编码就可以了
