176: A similar exploit might also be possible using sshd which lacks any code

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