Description Josh Bressers 2005-06-24 16:00:49 EDT
+++ 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:

Comment 1 Josh Bressers 2005-06-24 16:01:37 EDT
This issue should also affect FC3
Comment 2 Christian Iseli 2007-01-19 19:21:38 EST
This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Thanks.
