Doc Text:
A flaw was found in OpenSSH. A malicious or compromised server can write files to unintended locations on a client system during a recursive copy operation using the SFTP (Secure File Transfer Protocol) client. By returning crafted file paths, the remote server can trigger a directory traversal and force the client to store files outside the designated destination directory, potentially overwriting existing local files.
