Re: Fedora Atomic Host Two Week Release Announcement: 29.20190219.0

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


In this release, two major bugfixes are included:

1. runc container escape to host filesystem (CVE-2019-5736) [1], fixed with runc RPM version
2. rpm-ostree labeling of /home symlink to /var/home [2], fixed with rpm-ostree RPM version 2019.2-1.fc29

To reiterate, Atomic Host systems are protected from the runc exploit due to two lines of defense: SELinux, and /usr being mounted as read-only (see [3]). Thus, existing Atomic Host systems should not be affected.

The kernel update to 4.20.3-200.fc29, which introduced bugs that blocked the 20190204 release [4], is now being tracked at [5] and [6]. Since we have confirmed the ppc64le image boots with nested kvm/qemu virtualization on Power9 hardware, we have decided to release.

An example of the diff between this and the previous released version
(for x86_64) is:
