  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).

  Easily used incorrectly (e.g., incorrectly computing the correct maximum

data/libxvmc-1.0.12/wrapper/XvMCWrapper.c:303:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120). Risk is low because the source is a
  constant string.
