tag_insight = "USN-1732-1 fixed vulnerabilities in OpenSSL. The fix for CVE-2013-0166 and
  CVE-2012-2686 introduced a regression causing decryption failures on
  hardware supporting AES-NI. This update temporarily reverts the security
  fix pending further investigation. We apologize for the inconvenience.

  Original advisory details:

  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)
  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
  issue. A remote attacker could use this issue to perform
  plaintext-recovery attacks via analysis of timing data. (CVE-2013-0169)";
