Microsoft pptp vpn vulnerabilities Exploits in Action

2.1.1 Time Period
Fully updated systems using “Windows Update” and downloaded 
“service packs” to make systems current by installing ALL relevant 
updates available between March 1
st
2002 through June 30
th
2002. Note 
however this does not include the many scores of hot fixes and registry 
manipulations that are scattered throughout the various Microsoft Technet 
and Windows related websites. These were only the easy to access and 
install updates, as the majority of overworked administrators are likely to 
use. 
The same approach was used for Linux, Solaris and various BSD 
installs (FreeBSD & OpenBSD) using their various package update 
options.
