I haven't tried to reproduce the problem, but if it's affecting Jammy then we will need to SRU the fix, which means that we need a reproducer first. I took the liberty to backport the upstream patch and prepare a PPA build with it. Malcom, would you be able to test the following PPA and let us know if it fixes the problem? https://launchpad.net/~sergiodj/+archive/ubuntu/exim4-bug1974214 Thanks. ** Also affects: exim4 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: exim4 (Ubuntu Kinetic) Importance: Medium Status: Triaged ** Changed in: exim4 (Ubuntu Jammy) Status: New => Triaged ** Changed in: exim4 (Ubuntu Jammy) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1974214 Title: Segfaults on verify callout, in _gnutls_trust_list_get_issuer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/exim4/+bug/1974214/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
