NVD Description

Note: Versions mentioned in the description apply only to the upstream yaws package and not the yaws package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

Yaws 1.85 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.
