1.1 deraadt 121: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
122: libraries. These affect xterm and all other setuid-root programs that
123: use these libraries. The problems are associated with buffer overflows
124: in code that processes user-supplied data. The Xt library problems
125: include those fixed in TOG's recent public patch 3 for X11R6.3. All
126: releases of XFree86 up to and including 3.3.2 patch 1 and the version
127: distributed with OpenBSD are vulnerable to some or all of these
128: problems.
129: These problems are fixed in XFree86 patch 2.

139: problems of various kinds.

148: permit mmap'ing of immutable or append-only files which are otherwise

1.1 deraadt 164: As stated in CERT advisory VB-98.04, there are buffer
165: overrun problems in <strong>xterm</strong> related to the input-Method,
166: preeditType, and *Keymap resources. Additional buffer overruns exist in
167: the <strong>Xaw</strong> library related to the inputMethod and
168: preeditType resources. The xterm(1) problem represents a security
169: vulnerability for any platform where xterm is installed setuid-root
170: (as is the case for all OpenBSD platforms). The Xaw problem represents
171: a security vulnerability for any setuid-root program that uses the Xaw

173: these problems.
