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 (CVE-2016-2105).

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 (CVE-2016-2106).

A MITM attacker can use a padding oracle attack to decrypt traffic when
the connection uses an AES CBC cipher and the server support AES-NI
(CVE-2016-2107).

When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
a short invalid encoding can casuse allocation of large amounts of memory
potentially consuming excessive resources or exhausting memory
(CVE-2016-2109)");
