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.

An exception to this special treatment is if the URI has an authority
part (something that starts with "//" directly after what looks like a

Issue 1:
sh.bittable_size is a size_t but i is and int, which can result in
freelist == -1 if sh.bittable_size exceeds an int.
This seems to result in an OPENSSL_assert due to invalid allocation
size, so maybe that is "ok."
Worse, if sh.bittable_size is exactly 1<<31, then this becomes an
infinite loop (because 1<<31 is a negative int, so it can be shifted
right forever and sticks at -1).
Issue 2:
CRYPTO_secure_malloc_init() sets secure_mem_initialized=1 even when
sh_init() returns 0.
If sh_init() fails, we end up with secure_mem_initialized=1 but
sh.minsize=0. If you then call secure_malloc(), which then calls,
sh_malloc(), this then enters an infite loop since 0 << anything will
never be larger than size.
Issue 3:
That same sh_malloc loop will loop forever for a size greater
than size_t/2 because i will proceed (assuming sh.minsize=16):
i=16, 32, 64, ..., size_t/8, size_t/4, size_t/2, 0, 0, 0, 0, ....
This sequence will never be larger than "size".

In SCTP the code was only allowing a send of a close_notify alert if the

the close_notify alert to resend later when it is dry and then it returned
success. However because the application then thinks that the close_notify
alert has been successfully sent it never re-enters the DTLS code to
actually resend the alert. A much simpler solution is to just fail with a
retryable error in the event that the socket isn't dry. That way the
