FINAL RESULTS:

data/chrpath-0.16/chrpath.c:256:3:  [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(rpath, newpath);
data/chrpath-0.16/main.c:24:23:  [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.
#  define GETOPT_LONG getopt_long
data/chrpath-0.16/main.c:39:52:  [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.
#  define GETOPT_LONG(argc,argv,optstr,lopts,lidx) getopt(argc,argv,optstr)
data/chrpath-0.16/elf.c:49:9:  [2] (misc) open:
  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 = open(filename, flags);
data/chrpath-0.16/protos.h:18:12:  [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.
  unsigned char e_ident[EI_NIDENT];
data/chrpath-0.16/chrpath.c:105:10:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
      || read(fd, dyns, PHDR(p_filesz)) != (ssize_t)PHDR(p_filesz))
data/chrpath-0.16/chrpath.c:142:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if (read(fd, &shdr, sz_shdr) != (ssize_t)sz_shdr)
data/chrpath-0.16/chrpath.c:177:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  if (read(fd, strtab, SHDR_O(sh_size)) != (ssize_t)SHDR_O(sh_size))
data/chrpath-0.16/chrpath.c:231:14:  [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).
  rpathlen = strlen(rpath);
data/chrpath-0.16/chrpath.c:245:7:  [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).
  if (strlen(newpath) > rpathlen)
data/chrpath-0.16/elf.c:56:8:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
   if (read(fd, ehdr, EI_NIDENT) != EI_NIDENT)
data/chrpath-0.16/elf.c:80:8:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
   if (read(fd, ((char *)ehdr) + EI_NIDENT, sz_ehdr - EI_NIDENT)
data/chrpath-0.16/elf.c:112:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if (read(fd, phdr, sz_phdr) != (ssize_t)sz_phdr)
data/chrpath-0.16/killrpath.c:65:11:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
       || read(fd, dyns, PHDR(p_filesz)) != (ssize_t)PHDR(p_filesz))
