1.61      deraadt    38: A combination localhost+remote host security problem exists if a

                     42: A similar exploit might also be possible using sshd which lacks any code
                     43: for checking for deviations from the expected format in the .rhosts or
                     44: .shosts files, but we have not confirmed this yet.  The following two

                     60: not as important.
1.61      deraadt    61: This problem is fixed much better in OpenBSD-current, where the kernel's
                     62: symbolic link handling has been improved such that coredumping will not
                     63: create a file on the other side of a symbolic link.  Such a patch is not

                     69: will want this fix.  A bug in the vm system permits a file descriptor
                     70: opened read-only on a device, to later on be mmap(2)'d read-write, and
                     71: then modified.  This does not result in a security hole by itself, but
                     72: it does violate the safety semantics which securelevels are supposed to
1.78    ! deraadt    73: provide.  If a user manages to gain kmem group permissions, using this
