    Summary: LXD vulnerable to Race Condition

    Details: LXD before version 0.19-0ubuntu5 `doUidshiftIntoContainer()` has an unsafe `Chmod()` call that races against the stat in the `Filepath.Walk()` function. A symbolic link created in that window could cause any file on the system to have any mode of the attacker's choice. ### Specific Go Packages Affected github.com/lxc/lxd/shared
