FINAL RESULTS:

data/taggrepper-0.05/src/taggrepper.c:204:7:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
      printf(VERSION_STRING, PACKAGE_NAME, PACKAGE_VERSION);
data/taggrepper-0.05/src/taggrepper.c:179:9:  [3] (buffer) getopt_long:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
    c = getopt_long(argc, argv, "t:a:l:y:g:c:mrvh0",

data/taggrepper-0.05/src/files.c:268:9:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  len = strlen(filename);
