CVE-2016-2108

The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the "negative zero" issue.

Huzaifa Sidhpurwala, Hanno Böck, and David Benjamin discovered that OpenSSL incorrectly handled memory when decoding ASN.1 structures. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2108)

Juraj Somorovsky discovered that OpenSSL incorrectly performed padding when the connection uses the AES CBC cipher and the server supports AES-NI. A remote attacker could possibly use this issue to perform a padding oracle attack and decrypt traffic. (CVE-2016-2107)

Guido Vranken discovered that OpenSSL incorrectly handled large amounts of input data to the EVP_EncodeUpdate() function. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2105)

Guido Vranken discovered that OpenSSL incorrectly handled large amounts of input data to the EVP_EncryptUpdate() function. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2106)

Brian Carpenter discovered that OpenSSL incorrectly handled memory when ASN.1 data is read from a BIO. A remote attacker could possibly use this issue to cause memory consumption, resulting in a denial of service. (CVE-2016-2109)

As a security improvement, this update also modifies OpenSSL behaviour to reject DH key sizes below 1024 bits, preventing a possible downgrade attack.
