Vulnerability Assessment Summary
Checks for version of Apache

Detailed Explanation for this Vulnerability Assessment

The remote host appears to be running a version of
Apache 2.x which is older than 2.0.45

This version is vulnerable to various flaws :

- There is a denial of service attack which may permit
a possible hacker to disable this server remotely

- The httpd process leaks file descriptors to child processes,
such as CGI scripts. A possible hacker who has the ability to execute
arbitrary CGI scripts on this server (including PHP code) would
be able to write arbitrary data in the file pointed to (in particular,
the log files)

Solution : Upgrade to version 2.0.45
