Examining data/cube2font-1.5.1/src/shared/cube2font.c

FINAL RESULTS:

data/cube2font-1.5.1/src/shared/cube2font.c:23:5:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    vfprintf(stderr, fmt, v);
data/cube2font-1.5.1/src/shared/cube2font.c:84:9:  [2] (misc) fopen:
  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).
    f = fopen(filename, "wb");
data/cube2font-1.5.1/src/shared/cube2font.c:228:12:  [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.
    static char buf[7];
