  The fix for CVE-2016-2182 was incomplete and caused a regression when parsing
  certificates. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Shi Lei discovered that OpenSSL incorrectly handled the OCSP Status Request
extension. A remote attacker could possibly use this issue to cause memory
consumption, resulting in a denial of service. (CVE-2016-6304)
Guido Vranken discovered that OpenSSL used undefined behaviour when
performing pointer arithmetic. A remote attacker could possibly use this
issue to cause OpenSSL to crash, resulting in a denial of service. This
issue has only been addressed in Ubuntu 16.04 LTS in this update.
(CVE-2016-2177)
C&#233 sar Pereida, Billy Brumley, and Yuval Yarom discovered that OpenSSL
did not properly use constant-time operations when performing DSA signing.
A remote attacker could possibly use this issue to perform a cache-timing
attack and recover private DSA keys. (CVE-2016-2178)
Quan Luo discovered that OpenSSL did not properly restrict the lifetime
of queue entries in the DTLS implementation. A remote attacker could
possibly use this issue to consume memory, resulting in a denial of
service. (CVE-2016-2179)
Shi Lei discovered that OpenSSL incorrectly handled memory in the
TS_OBJ_print_bio() function. A remote attacker could possibly use this
issue to cause a denial of service. (CVE-2016-2180)
It was discovered that the OpenSSL incorrectly handled the DTLS anti-replay
feature. A remote attacker could possibly use this issue to cause a denial
of service. (CVE-2016-2181)
Shi Lei discovered that OpenSSL incorrectly validated division results. A
remote attacker could possibly use this issue to cause a denial of service.
(CVE-2016-2182)
Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES
ciphers were vulnerable to birthday attacks. A remote attacker could
possibly use this flaw to obtain clear text data from long encrypted
sessions. This update moves DES from the HIGH cipher list to MEDIUM.
(CVE-2016-2183)
Shi Lei discovered that OpenSSL incorrectly handled certain ticket lengths.
A remote attacker could use this issue to cause a denial of service.
(CVE-2016-6302)
Shi Lei discovered that OpenSSL incorrectly handled memory in the
MDC2_Update() function. A remote attacker could possibly use this issue to
cause a denial of service. (CVE-2016-6303)
Shi Lei discovered that OpenSSL incorrectly performed certain message
length checks. A remote attacker could possibly use this issue to cause a
denial of service. (CVE-2016-6306)");
