return true for characters > 127. I.e. they are allowing extended ASCII
characters through which then cause problems. E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably. Likewise letters with diacritical marks can also cause problems.
If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.
The implementation uses a single table with a bit for each of the defined
classes. These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set. They will
work for both signed and unsigned character inputs.

The OID for {1 3 6 1 5 5 8 1 2} HMAC-SHA1 (NID_hmac_sha1) is explicitly
referenced by RFC 2510, RFC 3370, and RFC 4210. This is essential for the
common implementations of CMP (Certificate Managing Protocol, RFC4210).
HMAC-MD5's OID {1 3 6 1 5 5 8 1 1} (NID_hmac_md5) is in the same branch and
it seems to generally exist (-> Internet search), but it is unclear where it is
actually defined as it appears not to be referenced by RFCs and practically
rather unused.
Those OIDs are both duplicates to OIDs from an RSA OID branch, which are already
included in builtin_pbe[]:
HMAC-SHA1 also has another OID defined in PKCS#5/RFC2898 (NID_hmacWithSHA1).
It is also unclear where the other OID for HMAC-MD5 (NID_hmacWithMD5) from the
RSA branch is officially specified, as only HMAC-SHA1 from PKCS#5 was found to be
defined. Anyway, HMAC-MD5 likely only plays a neglectable role in the future.

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 overflow can occur in the EVP_EncodeUpdate function which is used for
Base64 encoding of binary data. If an attacker is able to supply very large
amounts of input data then a length check can overflow resulting in a heap
corruption. Due to the very large amounts of data involved this will most
likely result in a crash.
Internally to OpenSSL the EVP_EncodeUpdate function is primarly used by the
PEM_write_bio* family of functions. These are mainly used within the
OpenSSL command line applications, so any application which processes
data from an untrusted source and outputs it as a PEM file should be
considered vulnerable to this issue.
User applications that call these APIs directly with large amounts of
untrusted data may also be vulnerable.

Reviewed-by: Richard Levitte <levitte@openssl.org>
An overflow can occur in the EVP_EncryptUpdate function. If an attacker is
able to supply very large amounts of input data after a previous call to
EVP_EncryptUpdate with a partial block then a length check can overflow
resulting in a heap corruption.
Following an analysis of all OpenSSL internal usage of the
EVP_EncryptUpdate function all usage is one of two forms.
The first form is like this:
EVP_EncryptInit()
EVP_EncryptUpdate()
i.e. where the EVP_EncryptUpdate() call is known to be the first called
function after an EVP_EncryptInit(), and therefore that specific call
must be safe.
The second form is where the length passed to EVP_EncryptUpdate() can be
seen from the code to be some small value and therefore there is no
possibility of an overflow.
Since all instances are one of these two forms, I believe that there can
be no overflows in internal code due to this problem.
It should be noted that EVP_DecryptUpdate() can call EVP_EncryptUpdate()
in certain code paths. Also EVP_CipherUpdate() is a synonym for
EVP_EncryptUpdate(). Therefore I have checked all instances of these
calls too, and came to the same conclusion, i.e. there are no instances
in internal usage where an overflow could occur.
This could still represent a security issue for end user code that calls
this function directly.
