Summary

OpenSSH 7.9 is susceptible to an issue where it accepts and displays arbitrary stderr output from a connected server.

An attacker can employ ANSI control codes to obscure vital information, such as the presence of additional files being transferred, potentially leading to unauthorized data exposure and manipulation.
