Summary
Youki: If /proc and /sys in the rootfs are symbolic links, they can potentially be exploited to gain access to the host root filesystem.
Details

Summary

If /proc and /sys in the rootfs are symbolic links, they can potentially be exploited to gain access to the host root filesystem.

Details

For security reasons, container creation should be prohibited if /proc or /sys in the rootfs is a symbolic link. I verified this behavior with youki. When /proc or /sys is a symbolic link, runc fails to create the container, whereas youki successfully creates it.

This is the fix related to this issue in runc.
