FEDORA-2026-b47b03e5c9 (mkvtoolnix-102.0-1.fc45) has been submitted as an update to Fedora 45. https://bodhi.fedoraproject.org/updates/FEDORA-2026-b47b03e5c9 Proposed as a Freeze Exception for 45-final by Fedora user rathann using the blocker tracking app because: This update fixes a high severity security bug and has been tested in rawhide for a couple of days already. FEDORA-2026-b56cbfe203 (libebml-1.4.7-1.fc44, libmatroska-1.7.2-1.fc44, and 1 more) has been submitted as an update to Fedora 44. https://bodhi.fedoraproject.org/updates/FEDORA-2026-b56cbfe203 FEDORA-2026-8918b368f4 (mkvtoolnix-96.0-2.fc43) has been submitted as an update to Fedora 43. https://bodhi.fedoraproject.org/updates/FEDORA-2026-8918b368f4 FEDORA-2026-b47b03e5c9 has been pushed to the Fedora 45 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2026-b47b03e5c9` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2026-b47b03e5c9 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. AGREED AcceptedFinalFreezeException Discussed at the 2026-10-12 (blocker / freeze exception) review meeting: As per previous proposal, this is accepted to keep the vulnerable version out of the frozen release repo and ensure people don't get it while updates-testing is disabled prior to release. We may reconsider our overall strategy for non-media CVE FEs later, though. https://meetbot-raw.fedoraproject.org//blocker-review_matrix_fedoraproject-org/2026-10-12/f45-blocker-review.2026-10-12-16.00.log.txt FEDORA-2026-b56cbfe203 (libebml-1.4.7-1.fc44, libmatroska-1.7.2-1.fc44, and 1 more) has been pushed to the Fedora 44 stable repository.
