{"id":"USN-3087-1","summary":"openssl vulnerabilities","details":"Shi Lei discovered that OpenSSL incorrectly handled the OCSP Status Request\nextension. A remote attacker could possibly use this issue to cause memory\nconsumption, resulting in a denial of service. (CVE-2016-6304)\n\nGuido Vranken discovered that OpenSSL used undefined behaviour when\nperforming pointer arithmetic. A remote attacker could possibly use this\nissue to cause OpenSSL to crash, resulting in a denial of service. This\nissue has only been addressed in Ubuntu 16.04 LTS in this update.\n(CVE-2016-2177)\n\nCésar Pereida, Billy Brumley, and Yuval Yarom discovered that OpenSSL\ndid not properly use constant-time operations when performing DSA signing.\nA remote attacker could possibly use this issue to perform a cache-timing\nattack and recover private DSA keys. (CVE-2016-2178)\n\nQuan Luo discovered that OpenSSL did not properly restrict the lifetime\nof queue entries in the DTLS implementation. A remote attacker could\npossibly use this issue to consume memory, resulting in a denial of\nservice. (CVE-2016-2179)\n\nShi Lei discovered that OpenSSL incorrectly handled memory in the\nTS_OBJ_print_bio() function. A remote attacker could possibly use this\nissue to cause a denial of service. (CVE-2016-2180)\n\nIt was discovered that the OpenSSL incorrectly handled the DTLS anti-replay\nfeature. A remote attacker could possibly use this issue to cause a denial\nof service. (CVE-2016-2181)\n\nShi Lei discovered that OpenSSL incorrectly validated division results. A\nremote attacker could possibly use this issue to cause a denial of service.\n(CVE-2016-2182)\n\nKarthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES\nciphers were vulnerable to birthday attacks. A remote attacker could\npossibly use this flaw to obtain clear text data from long encrypted\nsessions. This update moves DES from the HIGH cipher list to MEDIUM.\n(CVE-2016-2183)\n\nShi Lei discovered that OpenSSL incorrectly handled certain ticket lengths.\nA remote attacker could use this issue to cause a denial of service.\n(CVE-2016-6302)\n\nShi Lei discovered that OpenSSL incorrectly handled memory in the\nMDC2_Update() function. A remote attacker could possibly use this issue to\ncause a denial of service. (CVE-2016-6303)\n\nShi Lei discovered that OpenSSL incorrectly performed certain message\nlength checks. A remote attacker could possibly use this issue to cause a\ndenial of service.
