CVE-2016-2105 
Guido Vranken discovered that an overflow can occur in the function
EVP_EncodeUpdate(), used for Base64 encoding, if an attacker can
supply a large amount of data. This could lead to a heap corruption.

CVE-2016-2106 
Guido Vranken discovered that an overflow can occur in the function
EVP_EncryptUpdate() if an attacker can supply a large amount of data.
This could lead to a heap corruption.

CVE-2016-2107 
Juraj Somorovsky discovered a padding oracle in the AES CBC cipher
implementation based on the AES-NI instruction set. This could allow
an attacker to decrypt TLS traffic encrypted with one of the cipher
suites based on AES CBC.

CVE-2016-2108 
David Benjamin from Google discovered that two separate bugs in the
ASN.1 encoder, related to handling of negative zero integer values
and large universal tags, could lead to an out-of-bounds write.

CVE-2016-2109 
Brian Carpenter discovered that when ASN.1 data is read from a BIO
using functions such as d2i_CMS_bio(), a short invalid encoding can
cause allocation of large amounts of memory potentially consuming
excessive resources or exhausting memory.

Additional information about these issues can be found in the OpenSSL
security advisory at https://www.openssl.org/news/secadv/20160503.txt");
