FINAL RESULTS:

data/python-xattr-0.9.7/xattr/lib_build.c:405:13:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
            snprintf((char *)(namebuf + nsize), esize + 1,
data/python-xattr-0.9.7/xattr/lib_build.c:293:10:  [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(path,

data/python-xattr-0.9.7/xattr/lib_build.c:276:13:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    bytes = read(xfd, value, size);
data/python-xattr-0.9.7/xattr/lib_build.c:403:17:  [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).
        esize = strlen(entry->d_name);
