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