CVE Reference:   CVE-2006-0225   (Links to External Site)
Date:  Jan 25 2006
Impact:   Execution of arbitrary code via local system, User access via local system


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

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.
