Description

OpenSSH contains a flaw that may allow an attacker to execute arbitrary commands. The flaw is due to the way OpenSSH's scp utility handles file names during local-to-local copies. During the file name expansion, the utility does not properly sanitize filenames allowing a crafted file name with shell meta-characters. This can be used to trick a user into executing arbitrary commands under with a different set of (potentially higher) privileges.
