openssl: update to 1.0.2i (CVE-2016-6304 and more)
This update fixes several CVEs: * OCSP Status Request extension unbounded memory growth (CVE-2016-6304) * SWEET32 Mitigation (CVE-2016-2183) * OOB write in MDC2_Update() (CVE-2016-6303) * Malformed SHA512 ticket DoS (CVE-2016-6302) * OOB write in BN_bn2dec() (CVE-2016-2182) * OOB read in TS_OBJ_print_bio() (CVE-2016-2180) * DTLS buffered message DoS (CVE-2016-2179) * DTLS replay protection DoS (CVE-2016-2181) * Certificate message OOB reads (CVE-2016-6306) Of these, only CVE-2016-6304 is considered of high severity. Everything else is low. CVE-2016-2177 and CVE-2016-2178 were already fixed via local patches, which can be removed now. See https://www.openssl.org/news/secadv/20160922.txt for details. Some patches had to be refreshed and one compile error fix from upstream's OpenSSL_1_0_2-stable was required. The server.pem file is needed for test_dtls.

4Subject: [PATCH] Fix DSA, preserve BN_FLG_CONSTTIME
5
6Operations in the DSA signing algorithm should run in constant time in
7order to avoid side channel attacks. A flaw in the OpenSSL DSA
8implementation means that a non-constant time codepath is followed for
9certain operations. This has been demonstrated through a cache-timing
10attack to be sufficient for an attacker to recover the private DSA key.
