Description Mark J. Cox (Product Security) 2004-04-06 08:28:10 EDT
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:
Comment 1 Mark J. Cox (Product Security) 2004-04-06 08:30:05 EDT
We are currently evaluating this issue; in the meantime concerned
users can use sftp as an alternative way to copy files, or be careful
not to scp files from untrusted hosts.
Comment 2 Barry K. Nathan 2004-09-07 19:56:21 EDT
Is Red Hat still "evaluating this issue"? (I think Apple released a
patch to fix this vuln on Mac OS X earlier today, for what that's worth.)
Comment 6 Tim Powers 2005-05-18 09:48:31 EDT
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
on the solution and/or where to find the updated files,
please follow the link below. You may reopen this bug report
if the solution does not work for you.

Comment 7 Barry K. Nathan 2005-05-19 02:18:12 EDT
Will there be errata packages to fix this for RHEL 2.1?
Comment 8 Josh Bressers 2005-05-26 16:27:17 EDT
The fix for RHEL2.1 is now being tracked by bug 158915
