Looking at
http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-90Ar1.pdf
we see that in the CTR_DRBG_Update() algorithm (internal page number 51),
the provided input data is (after truncation to seedlen) xor-d with the
key and V vector (of length keylen and blocklen respectively). The comment
in ctr_XOR notes that xor-ing with 0 is the identity function, so we can
just ignore the case when the provided input is shorter than seedlen.
The code in ctr_XOR() then proceeds to xor the key with the input, up
to the amount of input present, and computes the remaining input that
could be used to xor with the V vector, before accessing a full 16-byte
stretch of the input vector and ignoring the calculated length. The correct
behavior is to respect the supplied input length and only xor the
indicated number of bytes.

In TLS mode of operation the padding value "pad" is obtained along with the
maximum possible padding value "maxpad". If pad > maxpad then the data is
invalid. However we must continue anyway because this is constant time code.
We calculate the payload length like this:
inp_len = len - (SHA_DIGEST_LENGTH + pad + 1);
However if pad is invalid then inp_len ends up -ve (actually large +ve
because it is a size_t).
Later we do this:
/* verify HMAC */
out += inp_len;
len -= inp_len;
This ends up with "out" pointing before the buffer which is undefined
behaviour. Next we calculate "p" like this:
unsigned char *p =
out + len - 1 - maxpad - SHA256_DIGEST_LENGTH;
Because of the "out + len" term the -ve inp_len value is cancelled out
so "p" points to valid memory (although technically the pointer arithmetic
is undefined behaviour again).
We only ever then dereference "p" and never "out" directly so there is
never an invalid read based on the bad pointer - so there is no security
issue.
This commit fixes the undefined behaviour by ensuring we use maxpad in
place of pad, if the supplied pad is invalid.

To handle paths that contain devices (for example, C:/foo/bar.pem on

The "file" scheme does the same kind of thing to pick out the path
part of the URI.
An exception to this special treatment is if the URI has an authority
part (something that starts with "//" directly after what looks like a
scheme). Such URIs will never be treated as plain file paths.
