FINAL RESULTS:

data/libtime-moment-perl-0.44/ppport.h:7380:14:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    retval = vsnprintf(buffer, len, format, ap);
data/libtime-moment-perl-0.44/ppport.h:7382:14:  [4] (format) vsprintf:
  Potential format string problem (CWE-134). Make format string constant.
    retval = vsprintf(buffer, format, ap);

  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.
