Apache Tomcat 7.0.x < 7.0.28 Multiple DoS

medium Nessus Plugin ID 62985

Language:

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.

Solution

Upgrade to Apache Tomcat version 7.0.28 or later.
