USN-3475-1: OpenSSL vulnerabilities
- Canonical Ubuntu 14.04
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 performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied to Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04. (CVE-2017-3736)
