FINAL RESULTS:

data/gdmap-0.8.1/src/colors.c:161:24:  [3] (buffer) g_get_home_dir:
  This function is synonymous with 'getenv("HOME")';it returns untrustable
  input if the environment can beset by an attacker. It can have any content
  and length, and the same variable can be set more than once (CWE-807,
  CWE-20). Check environment variables carefully before using them.
    const char* home = g_get_home_dir();

data/gdmap-0.8.1/src/colors.c:208:13:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
        r = atoi(attr);

data/gdmap-0.8.1/src/preferences.c:58:18:  [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).
            fd = fopen(filename, "w");
data/gdmap-0.8.1/src/utils.c:150:7:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
      memcpy(result+len, sep, add);
data/gdmap-0.8.1/src/utils.c:153:5:  [2] (buffer) memcpy:

  Make sure destination can always hold the source data.
    memcpy(result+len, text, l);
data/gdmap-0.8.1/src/tree.c:168:25:  [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).
            if (dirname[strlen(dirname)-1] == '/')
