The remote host is using a version of mod_ssl which is
older than 2.8.7.

This version is vulnerable to a buffer overflow which,
albeit difficult to exploit, may allow an attacker
to obtain a shell on this host.

*** Some vendors patched older versions of mod_ssl, so this
*** might be a false positive. Check with your vendor to determine
*** if you have a version of mod_ssl that is patched for this 
*** vulnerability


Solution : Upgrade to version 2.8.7 or newer
Risk factor : High";
