Summary
openssl regression
Details

USN-3087-1 fixed vulnerabilities in OpenSSL. 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)

César 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 TSOBJprint_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)
