-<overview>
-<p>The program uses input from the user, propagated via a global variable, as a format string for <code>printf</code> style functions. 
-This can lead to buffer overflows or data representation problems. An attacker can exploit this weakness to crash the program, 
-disclose information or even execute arbitrary code.</p>
-
-<p>This rule only identifies inputs from the user that are transferred through global variables before being used in <code>printf</code> style functions.
-Analyzing the flow of data through global variables is more prone to errors and so this rule may identify some examples of code where 
-the input is not really from the user. For example, when a global variable is set in two places, one that comes from the user and one that does not.
-In this case we would mark all usages of the global variable as input from the user, but the input from the user may always came after the call to the
-<code>printf</code> style functions.</p>
-
-<p>The results of this rule should be considered alongside the related rule "Uncontrolled format string" which tracks the flow of the 
-values input by a user, excluding global variables, until the values are used as the format argument for a <code>printf</code> like function call.</p>
-
-</overview>
-<recommendation>
-<p>Use constant expressions as the format strings. If you need to print a value from the user, use <code>printf("%s", value_from_user)</code>.</p>
