  • SECURITY FIX
    ! If you rely on the system securelevels as described in init(8), you ! will want this fix. A bug in the vm system permits a file descriptor ! opened read-only on a device, to later on be mmap(2)'d read-write, and ! then modified. This does not result in a security hole by itself, but ! it does violate the safety semantics which securelevels are supposed to ! provide. If a user manages to gain kmem group permissions, using this ! problem they can then gain root trivially. A kernel patch is available which corrects this behaviour (this is revision 2 of this patch). --- 65,76 ----
