Public bug reported: [Impact]
* OpenSSL 1.1.1 is an LTS release upstream, which will continue to receive security support for much longer than 1.1.0 series will. * OpenSSL 1.1.1 comes with support for TLS v1.3 which is expected to be rapidly adopted due to increased set of supported hashes & algoes, as well as improved handshake [re-]negotiation. * OpenSSL 1.1.1 comes with improved hw-acceleration capabilities. * OpenSSL 1.1.1 is ABI/API compatible with 1.1.0, however some software is sensitive to the negotiation handshake and may either need patches/improvements or clamp-down to maximum v1.2. [Test Case] * Rebuild all reverse dependencies * Execute autopkg tests for all of them * Clamp down to TLS v1.2 software that does not support TLS v1.3 (e.g. mongodb) * Backport TLS v1.3 support patches, where applicable [Regression Potential] * Connectivity interop is the biggest issues which will be unavoidable with introducing TLS v1.3. However, tests on cosmic demonstrate that curl/nginx/google-chrome/mozilla-firefox connect and negotiate TLS v1.3 without issues. * Mitigation of discovered connectivity issues will be possible by clamping down to TLS v1.2 in either server-side or client-side software or by backporting relevant support fixes [Other Info] * Previous FFe for OpenSSL in 18.10 is at https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1793092 * TLS v1.3 support in NSS is expected to make it to 18.04 via security updates * TLS v1.3 support in GnuTLS is expected to be available in 19.04 ** Affects: openssl (Ubuntu) Importance: Undecided Status: New ** Tags: bionic ** Tags added: bionic -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssl in Ubuntu. https://bugs.launchpad.net/bugs/1797386 Title: SRU OpenSSL 1.1.1 to 18.04 LTS Status in openssl package in Ubuntu: New Bug description: [Impact] * OpenSSL 1.1.1 is an LTS release upstream, which will continue to receive security support for much longer than 1.1.0 series will. * OpenSSL 1.1.1 comes with support for TLS v1.3 which is expected to be rapidly adopted due to increased set of supported hashes & algoes, as well as improved handshake [re-]negotiation. * OpenSSL 1.1.1 comes with improved hw-acceleration capabilities. * OpenSSL 1.1.1 is ABI/API compatible with 1.1.0, however some software is sensitive to the negotiation handshake and may either need patches/improvements or clamp-down to maximum v1.2.
