FINAL RESULTS:

data/libxv-1.0.11/include/X11/extensions/Xvlib.h:128:5:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
    char guid[16];              /* Globally Unique IDentifier */

  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
