SeaCat Technology and the Latest OpenSSL Update (1.1.0e)
February 21, 2017
OpenSSL released a new version on February 16, 2017. The new version fixed one high-severity issue regarding renegotiation of the Encrypt-then-MAC (EtM) extension, an approach to authenticated encryption. The vulnerability is identified as CVE-2017-3733. Several, not yet known, cipher suites are affected; therefore disabling affected cipher suites can not be used as a workaround.
TeskaLabs’ SeaCat technology uses the 1.0.2 series for its cryptography library, so this update does not affect our technology in any way.
Your systems and applications are affected if they use OpenSSL 1.1.0 series. EtM is the strongest approach to authenticated encryption. We strongly recommend you to update to the latest version.
Your application developers or operators should inform you about update requirements. If you have any concern about the security of your systems, we are ready to help you.

OpenSSL DROWN Vulnerability Affects Millions of HTTPS Websites and Software Supporting SSLv2 (CVE-2016-0800)
DROWN is caused by legacy OpenSSL SSLv2 protocol, known to have many deficiencies. Security experts have recommended to turn it off, but apparently many servers still support it because disabling SSLv2 requires non-default reconfiguration of the SSL cryptographic settings which is not easy for common IT people who have limited security knowledge and don’t know the location to disable this protocol and the way to disable it.
