(Sun Issues Fix for rcp) OpenSSH scp Double Shell Character Expansion During Local-to-Local Copying May Let Local Users Gain Elevated Privileges in Certain Cases
SecurityTracker Alert ID:  1018364
SecurityTracker URL:  http://securitytracker.com/id/1018364
CVE Reference:   CVE-2006-0225   (Links to External Site)
Date:  Jul 11 2007
Impact:   Execution of arbitrary code via local system, User access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in scp in OpenSSH. A local user may be able to obtain elevated privileges in certain cases. Rcp is affected.

When performing local-to-local copying functions, scp expands shell characters in the filename twice before making a system() call. A filename that contains specially crafted characters may cause arbitrary commands to be executed.

If scp is used to transfer untrusted files or directories, a local user may be able to cause arbitrary code to be executed with the privileges of the process running scp.
