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 casuse allocation of large amounts of memory potentially consuming excessive resources or exhausting memory.
CVE-2016-2176
Guido Vranken discovered that ASN.1 Strings that are over 1024 bytes can cause an overread in applications using the X509_NAME_oneline() function on EBCDIC systems. This could result in arbitrary stack data being returned in the buffer.
