Description

** DISPUTED ** scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument.

Note from the SUSE Security Team

This issue has been disputed. The 'scp' protocol allows shell execution, it can not really be made secure against users doing more than filetransfer. Please consider using 'sftp' instead.
