USN-2914-1

Yuval Yarom, Daniel Genkin, and Nadia Heninger discovered that OpenSSL was vulnerable to a side-channel attack on modular exponentiation. On certain CPUs, a local attacker could possibly use this issue to recover RSA keys. This flaw is known as CacheBleed. (CVE-2016-0702)

Adam Langley discovered that OpenSSL incorrectly handled memory when parsing DSA private keys. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-0705)

Guido Vranken discovered that OpenSSL incorrectly handled hex digit calculation in the BN_hex2bn 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-2016-0797)

Emilia Käsper discovered that OpenSSL incorrectly handled memory when performing SRP user database lookups. A remote attacker could possibly use this issue to cause OpenSSL to consume memory, resulting in a denial of service. (CVE-2016-0798)

Guido Vranken discovered that OpenSSL incorrectly handled memory when printing very long strings. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-0799)
