X Window System
The scanner attempts to connect to a host
Risk: High
Fix: Key-based protection schemes for the X server, such as xauth, generate an
obscure authorization scheme instead of a host-based one. This tells the server
not to allow an application to use the display unless it can produce the required
string. This string is usually stored in a file that can only be read by a
particular user, in effect restricting the display to that one user. When an
additional user needs to use the same display, the string can be given to that user.
