The remote web server is affected by a remote denial of service vulnerabily


Versions of Tomcat 7.0.x earlier than 7.0.28 are potentially affected by a remote denial of service vulnerability:

- A flaw exists within the parseHeaders() function that could allow for a crafted header to cause a remote denial of service (CVE-2012-2733)

- An error exists related to the 'NIO' connector when HTTPS and 'sendfile' are enabled that can force the application into an infinite loop. (CVE-2012-4534)


Upgrade to Apache Tomcat 7.0.28 or later.
