1.1 deraadt 131: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
132: libraries. These affect xterm and all other setuid-root programs that
133: use these libraries. The problems are associated with buffer overflows
134: in code that processes user-supplied data. The Xt library problems
135: include those fixed in TOG's recent public patch 3 for X11R6.3. All
136: releases of XFree86 up to and including 3.3.2 patch 1 and the version
137: distributed with OpenBSD are vulnerable to some or all of these
138: problems.
139: These problems are fixed in XFree86 patch 2.

1.1 deraadt 146: The kill(2) system call previously would permit a large set of signals to
147: be delivered to setuid or setgid processes. If such processes were using
148: those signals in dubious ways, this could have resulted in security
149: problems of various kinds.

1.1 deraadt 156: A possible new security problem exists if you rely on securelevels and
157: immutable or append-only files or character devices. The fix does not
158: permit mmap'ing of immutable or append-only files which are otherwise
1.17 pvalchev 159: writable, as the VM system will bypass the meaning of the file flags

1.28 naddy 173: <li><font color="#009000"><strong>SECURITY FIX</strong></font><br>
1.1 deraadt 174: As stated in CERT advisory VB-98.04, there are buffer
175: overrun problems in <strong>xterm</strong> related to the input-Method,
176: preeditType, and *Keymap resources. Additional buffer overruns exist in
177: the <strong>Xaw</strong> library related to the inputMethod and
178: preeditType resources. The xterm(1) problem represents a security
179: vulnerability for any platform where xterm is installed setuid-root
180: (as is the case for all OpenBSD platforms). The Xaw problem represents
181: a security vulnerability for any setuid-root program that uses the Xaw
182: library (including xterm). Patch1 from XFree86 3.3.2 corrects
183: these problems.
