With the EVP_EncodeUpdate function it is the caller's responsibility to

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.

CVE-2016-2105
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.

One category of warnings is particularly interesting - C4701 (potentially

that there's a code path which results in uninitialized variables being used

hard to debug so it's rational to fix these issues.

Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.
Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.

Start ensuring all OpenSSL "free" routines allow NULL, and remove
any if check before calling them.
This gets DH_free, DSA_free, RSA_free

This tests the unwrap algorithm with an invalid key. The result should
be rejected without returning any plaintext.

Calling EVP_DigestInit_ex which has already had the digest set up for it
should be possible. You are supposed to be able to pass NULL for the type.
However currently this seg faults.

Add support for skipping disabled algorithms: if an attempt to load a
public or private key results in an unknown algorithm error then any
test using that key is automatically skipped.

When OpenSSL is configured with no-ec, then the new evp_extra_test fails to
pass. This change adds appropriate OPENSSL_NO_EC guards around the code.

Add two new keywords "PublicKey" and "PrivateKey". These will load a key
in PEM format from the lines immediately following the keyword and assign
it a name according to the value. These will be used later for public and
private key testing operations.
Add tests for Sign, Verify, VerifyRecover and Decrypt.

Disabling HMAC doesn't work. If it did it would end up disabling a lot of
OpenSSL functionality (it is required for all versions of TLS for example).
