ABV.ITERATOR SV.TAINTED.LOOP_BOUND

 

Compass/ROSE

  

Could be configured to catch violations of this rule. The way to catch the noncompliant code example is to first hunt for example code that follows this pattern:

   for (LPWSTR pwszTemp = pwszPath + 2; *pwszTemp != L'\\';
*pwszTemp++;)

In particular, the iteration variable is a pointer, it gets incremented, and the loop condition does not set an upper bound on the pointer. Once this case is handled, we can handle cases like the real noncompliant code example, which is effectively the same semantics, just different syntax.
