The remote host is using a version vulnerable of mod_ssl which is
older than 2.8.19. There is a format string condition in the
log functions of the remote module which may allow an attacker to
execute arbitrary code on the remote 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 2.8.19 or newer
Risk factor : High";
