102: preeditType, and *Keymap resources. Additional buffer overruns exist in

1.1 deraadt 164: A combination localhost+remote host security problem exists if a

1.1 deraadt 166: file to be created via a symbolic link with a specific kind of corefile,
167: and then subsequently uses rsh/rlogin to enter the machine from remote.
168: A similar exploit might also be possible using sshd which lacks any code
169: for checking for deviations from the expected format in the .rhosts or
170: .shosts files, but we have not confirmed this yet. The following two

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