1.1 deraadt 161: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
162: libraries. These affect xterm and all other setuid-root programs that

1.1 deraadt 208: As stated in CERT advisory VB-98.04, there are buffer
209: overrun problems in <strong>xterm</strong> related to the input-Method,
210: preeditType, and *Keymap resources. Additional buffer overruns exist in
211: the <strong>Xaw</strong> library related to the inputMethod and
212: preeditType resources. The xterm(1) problem represents a security
213: vulnerability for any platform where xterm is installed setuid-root
214: (as is the case for all OpenBSD platforms). The Xaw problem represents
215: a security vulnerability for any setuid-root program that uses the Xaw
