Apache Tomcat 7.0.x < 7.0.28 Multiple DoS

Synopsis :

The remote Apache Tomcat server is affected by multiple remote denial
of service vulnerabilities.

Description :

According to its self-reported version number, the instance of Apache
Tomcat 7.0 listening on the remote host is prior to 7.0.28. It is,
therefore, affected by the following vulnerabilities :

- A flaw exists within the parseHeaders() function that
allows an attacker, via 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)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
