CVE-2015-3196: Canonical Ubuntu Linux

Medium severity, CVSS 4.3. EPSS: 13.5% chance of exploitation in the next 30 days.

ssl/s3_clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service (race condition and double free) via a crafted ServerKeyExchange message.
