168: and then subsequently uses rsh/rlogin to enter the machine from remote.
169: A similar exploit might also be possible using sshd which lacks any code
170: for checking for deviations from the expected format in the .rhosts or
171: .shosts files, but we have not confirmed this yet. The following two

185: If the
186: first patch is used to stop setuid coredumps, then the second patch is
187: not as important.
188: This problem is fixed much better in OpenBSD-current, where the kernel's
189: symbolic link handling has been improved such that coredumping will not
190: create a file on the other side of a symbolic link. Such a patch is not
191: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>

199: does not result in a security hole by itself, but it does violate the
