It is in the SRU queue and the current ETA is April 15 to land in the proposed pocket (archive proposed not security proposed ppa), there is a caveat that the recent xz backdoor has caused some "fun" on the archive side and could potentially cause some delays.

However, because the fix makes mount rules in apparmor policy be treated more restrictively than they were prior to this update, we would like these packages to gain more widespread testing. Risk of Regression: The update for this issue causes the apparmor parser, the tool that translates written policy into the enforcement data structures used by the kernel, to generate more strict policy for mount rules, like the example below. They are not common in apparmor policy generally, but can appear in policies written for container managers to restrict containers, and thus can potentially break container startup. The packages prepared for focal-proposed and jammy-proposed have tested with the versions of snapd, lxc, libvirt, and docker in the ubuntu archive, but conainter managers outside of the ubunty archive may run into issues, hence the need for testing and policy adjustments. Original Report: The rule mount options=(rw,make-slave) -> **, ends up allowing mount -t proc proc /mnt which it shouldn't as it should be restricted to commands with a make- slave flag To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/1597017/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
