The remote host appears to be running a version of
Apache which is older than 1.3.27

There are several flaws in this version, you should
upgrade to 1.3.27 or newer.

*** Note that Nessus solely relied on the version number
*** of the remote server to issue this warning. This might
*** be a false positive

Solution : Upgrade to version 1.3.27
