*** This bug is a security vulnerability *** Public security bug reported:
https://community.letsencrypt.org/t/openssl-client-compatibility- changes-for-let-s-encrypt-certificates/143816 Currently gnutls28 in bionic and earlier will not establish a connection, if any parts of the trust chain have expired, even though alternative non-expired chains are available. This has been fixed in GnuTLS 3.6.14, but probably should be backported to bionic and earlier if it was not already been done so. https://gitlab.com/gnutls/gnutls/-/issues/1008 https://gitlab.com/gnutls/gnutls/-/merge_requests/1271 ** Affects: gnutls28 (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: gnutls28 (Ubuntu Precise) Importance: Undecided Status: New ** Affects: gnutls28 (Ubuntu Trusty) Importance: Undecided Status: New ** Affects: gnutls28 (Ubuntu Xenial) Importance: Undecided Status: New ** Affects: gnutls28 (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: gnutls28 (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: gnutls28 (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: gnutls28 (Ubuntu Xenial) Importance: Undecided Status: New ** Also affects: gnutls28 (Ubuntu Precise) Importance: Undecided Status: New ** Changed in: gnutls28 (Ubuntu) Status: New => Fix Released ** Information type changed from Public to Public Security -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928648 Title: expiring trust anchor compatibility issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnutls28/+bug/1928648/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
