<p>CVE-2018-14618: NTLM password overflow via integer overflow</p>
<p>The internal function Curl_ntlm_core_mk_nt_hash multiplies the length
of the password by two (SUM) to figure out how large temporary storage
area to allocate from the heap.</p>
<p>The length value is then subsequently used to iterate over the
password and generate output into the allocated storage buffer. On
systems with a 32 bit size_t, the math to calculate SUM triggers an
integer overflow when the password length exceeds 2GB (2^31 bytes).
This integer overflow usually causes a very small buffer to actually
get allocated instead of the intended very huge one, making the use of
that buffer end up in a heap buffer overflow.</p>
<p>This bug is almost identical to CVE-2017-8816.</p>
