USN-3475-1: OpenSSL vulnerabilities
06 November 2017
Several security issues were fixed in OpenSSL.

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)

squaring procedure. While unlikely, a remote attacker could possibly use
this issue to recover private keys. This issue only applied to Ubuntu 16.04

The problem can be corrected by updating your system to the following package versions:
After a standard system update you need to reboot your computer to make
