Details

USN-3611-1 fixed a vulnerability in OpenSSL. This update provides
the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

It was discovered that OpenSSL incorrectly parsed the IPAddressFamily
extension in X.509 certificates, resulting in an erroneous display of the
certificate in text format. (CVE-2017-3735)

It was discovered that OpenSSL incorrectly handled certain ASN.1 types. A
remote attacker could possibly use this issue to cause a denial of service.
(CVE-2018-0739)
