With the EVP_EncodeUpdate function it is the caller's responsibility to determine how big the output buffer should be. The function writes the amount actually used to |*outl|. However this could go negative with a sufficiently large value for |inl|. We add a check for this error condition. Reviewed-by: NRichard Levitte <levitte@openssl.org>

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. Issue reported by Guido Vranken.

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. CVE-2016-2106 Issue reported by Guido Vranken. Reviewed-by: NTim Hudson <tjh@openssl.org>

Fix some of the variables to be (s)size_t, so that more than 1GB of secure memory can be allocated. The arena has to be a power of 2, and 2GB fails because it ends up being a negative 32-bit signed number. The |too_late| flag is not strictly necessary; it is easy to figure out if something is secure memory by looking at the arena. As before, secure memory allocations will not fail, but now they can be freed correctly. Once initialized, secure memory can still be used, even if allocations occured before initialization.

The srp application created an uninitialised DB_ATTR object and then passed it to the load_index function which attempted to read it. A DB_ATTR object only contains a single field called "unique_subject". AFAICT this attribute is unused in the SRP case, and therefore it would be better to pass a NULL DB_ATTR to load_index (which handles that case gracefully).

We should only copy parameters and keys if the group is set. Otherwise they don't really make any sense. Previously we copied the private key regardless of whether the group was set...but if it wasn't a NULL ptr deref could occur. It's unclear whether we could ever get into that situation, but since we were already checking it for the public key we should be consistent. Reviewed-by: NRich Salz <rsalz@openssl.org>
