+++ 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.
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:
This issue should also affect RHEL2.1 and RHEL3
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
