This vulnerability can be mitigated by disabling UTF-8 support in XTerm configuration. An entry such as "XTerm.vt100.utf8: false" in Xresources will disable UTF-8. This can be set as a system default in /etc/X11/Xresources, or per-user in ~/.Xresources. Note that this setting can still be overridden if xterm is invoked with the "-u8" command line option, so the mitigation may not protect all use cases.
