flatpak: Sandbox bypass via recent VFS-manipulating syscalls

A flaw was found in the flatpak package. It is susceptible to a software flaw that can deceive portals and other host-OS services into treating the flatpak app as an ordinary, non-sandboxed host-OS process. This flaw allows the escalation of privileges that the corresponding services presume the...
