Examining data/erlang-p1-zlib-1.0.8/c_src/ezlib_drv.c

FINAL RESULTS:

data/erlang-p1-zlib-1.0.8/c_src/ezlib_drv.c:98:13:  [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).
	    rlen = strlen(errstr) + 1;				\
data/erlang-p1-zlib-1.0.8/c_src/ezlib_drv.c:101:6:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	    strncpy(b->orig_bytes + 1, errstr, rlen - 1);	\
