Description Josh Bressers 2005-05-26 20:26:22 UTC
+++ This bug was initially created as a clone of Bug #120147 +++

Back in 2000 it was reported that a malicious ssh server could cause
scp to write to arbitrary files outside of the current directory. 
See:    
http://cert.uni-stuttgart.de/archive/bugtraq/2000/09/msg00499.html

This is a valid behaviour of the rcp protocol.

The issue was rediscovered in Mar 2004 and discussed amongst OSS
vendors, with Markus Friedl from OpenBSD writing a proposed patch for
this issue but warned that it needed a lot of testing:
