What is CVE-2019-6109?

A vulnerability in OpenSSH 7.9 allows an adversary to exploit the progress display of file transfers. Through crafted object names, a malicious server or Man-in-the-Middle attacker can manipulate the output, potentially obscuring additional files being transferred. This flaw stems from insufficient character encoding within the refresh_progress_meter() function in progressmeter.c, posing risks during data transmission that may go unnoticed by the user.
