Examining data/mac-robber-1.02/mac-robber.c

FINAL RESULTS:

data/mac-robber-1.02/mac-robber.c:277:20:  [5] (race) readlink:
  This accepts filename arguments; if an attacker can move those files or
  change the link content, a race condition results. Also, it does not
  terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
            llen = readlink(curpath, linkpath, LINKPATH_LEN - 1);
data/mac-robber-1.02/mac-robber.c:321:18:  [3] (buffer) getopt:
  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.
    while ((ch = getopt(argc, argv, "V")) > 0) {
data/mac-robber-1.02/mac-robber.c:89:5:  [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.
    char hostnamebuf[BUFSIZ];
data/mac-robber-1.02/mac-robber.c:131:5:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
    strcpy(ls, "----------");
data/mac-robber-1.02/mac-robber.c:251:9:  [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.
        char ls[LS_SIZE];
data/mac-robber-1.02/mac-robber.c:231:15:  [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).
    dir_len = strlen(dir);
data/mac-robber-1.02/mac-robber.c:247:5:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
    strncpy(curpath, dir, path_len);
data/mac-robber-1.02/mac-robber.c:260:9:  [1] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings.
        strncat(curpath, dp->d_name, path_len);
data/mac-robber-1.02/mac-robber.c:296:13:  [1] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is low because the source is a
  constant character.
            strncat(curpath, "/", path_len);
data/mac-robber-1.02/mac-robber.c:348:15:  [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(argv[optind]);
data/mac-robber-1.02/mac-robber.c:354:13:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
            strncpy(dir, argv[optind], len + 1);
data/mac-robber-1.02/mac-robber.c:355:13:  [1] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is low because the source is a
  constant character.
            strncat(dir, "/", len + 2);
