-Subject: [PATCH 1/1] nsenter: clone /proc/self/exe to avoid exposing host
- binary to container
-
-There are quite a few circumstances where /proc/self/exe pointing to a
-pretty important container binary is a _bad_ thing, so to avoid this we
-have to make a copy (preferably doing self-clean-up and not being
-writeable).
-
-As a hotfix we require memfd_create(2), but we can always extend this to
-use a scratch MNT_DETACH overlayfs or tmpfs. The main downside to this
-approach is no page-cache sharing for the runc binary (which overlayfs
-would give us) but this is far less complicated.
-
-This is only done during nsenter so that it happens transparently to the
-Go code, and any libcontainer users benefit from it. This also makes
-ExtraFiles and --preserve-fds handling trivial (because we don't need to
-worry about it).
-
-Fixes: CVE-2019-5736

-Subject: [PATCH] rootfs: umount all procfs and sysfs with --no-pivot
-
-When creating a new user namespace, the kernel doesn't allow to mount
-a new procfs or sysfs file system if there is not already one instance
-fully visible in the current mount namespace.
-
-When using --no-pivot we were effectively inhibiting this protection
-from the kernel, as /proc and /sys from the host are still present in
-the container mount namespace.
-
-A container without full access to /proc could then create a new user
-namespace, and from there able to mount a fully visible /proc, bypassing
-the limitations in the container.
-
-A simple reproducer for this issue is:
-
-unshare -mrfp sh -c "mount -t proc none /proc && echo c > /proc/sysrq-trigger"
-
