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.

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