Adam Langley and Wolfgang Ettlingers discovered that OpenSSL incorrectly handled certain crafted CBC data when used with AES-NI. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 12.10. (CVE-2012-2686)

Stephen Henson discovered that OpenSSL incorrectly performed signature verification for OCSP responses. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service.
(CVE-2013-0166)

Nadhem Alfardan and Kenny Paterson discovered that the TLS protocol as used in OpenSSL was vulnerable to a timing side-channel attack known as the ‘Lucky Thirteen’ issue. A remote attacker could use this issue to perform plaintext-recovery attacks via analysis of timing data.
(CVE-2013-0169).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
