FINAL RESULTS:

data/libsocket6-perl-0.29/getnameinfo.c:42:6:  [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).

data/libsocket6-perl-0.29/inet_ntop.c:85:21:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.
        if ((size_t)sprintf(tmp, fmt, src[0], src[1], src[2], src[3]) >= size)
data/libsocket6-perl-0.29/inet_ntop.c:90:9:  [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

data/libsocket6-perl-0.29/inet_ntop.c:187:9:  [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).

data/libsocket6-perl-0.29/getaddrinfo.c:112:19:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	    port = htons(atoi(servname));
data/libsocket6-perl-0.29/getnameinfo.c:35:5:  [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.

  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.

data/libsocket6-perl-0.29/getnameinfo.c:39:6:  [1] (buffer) strlen:

  perform an over-read (it could cause a crash if unprotected) (CWE-126).
