CVE-2016-2107: Canonical Ubuntu Linux

Medium severity, CVSS 5.9. EPSS: 89.1% chance of exploitation in the next 30 days.

The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.
