Security Advisory Description
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c. (CVE-2019-6109)
Impact
Missing character encoding in the progress display allows for spoofing of OpenSSH SCP client output.
