FINAL RESULTS:

data/lua-filesystem-1.8.0/src/lfs.c:1089:13:  [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.
    tsize = readlink(file, target, size);
data/lua-filesystem-1.8.0/src/lfs.c:430:3:  [4] (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).
  strcpy(ln, path);
data/lua-filesystem-1.8.0/src/lfs.c:431:3:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
  strcat(ln, lockfile);
data/lua-filesystem-1.8.0/src/lfs.c:472:3:  [4] (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).
  strcpy(ln, path);
data/lua-filesystem-1.8.0/src/lfs.c:473:3:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
  strcat(ln, lockfile);
data/lua-filesystem-1.8.0/src/lfs.c:722:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(d->pattern, "%s/*", path);
data/lua-filesystem-1.8.0/src/lfs.c:117:3:  [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 pattern[MAX_PATH + 1];
data/lua-filesystem-1.8.0/src/lfs.c:924:10:  [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 perms[10] = "---------";
data/lua-filesystem-1.8.0/src/lfs.c:948:10:  [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

  static char perms[10] = "---------";
data/lua-filesystem-1.8.0/src/lfs.c:424:32:  [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).
  ln = (char *) malloc(pathl + strlen(lockfile) + 1);
data/lua-filesystem-1.8.0/src/lfs.c:466:32:  [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).
  ln = (char *) malloc(pathl + strlen(lockfile) + 1);
data/lua-filesystem-1.8.0/src/lfs.c:719:7:  [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).
