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

1.1 deraadt 141: The kill(2) system call previously would permit a large set of signals to
142: be delivered to setuid or setgid processes. If such processes were using
143: those signals in dubious ways, this could have resulted in security
144: problems of various kinds.

1.1 deraadt 151: A possible new security problem exists if you rely on securelevels and
152: immutable or append-only files or character devices. The fix does not
153: permit mmap'ing of immutable or append-only files which are otherwise
1.17 pvalchev 154: writable, as the VM system will bypass the meaning of the file flags

1.28 naddy 168: <li><font color="#009000"><strong>SECURITY FIX</strong></font><br>
1.1 deraadt 169: As stated in CERT advisory VB-98.04, there are buffer
170: overrun problems in <strong>xterm</strong> related to the input-Method,
171: preeditType, and *Keymap resources. Additional buffer overruns exist in
172: the <strong>Xaw</strong> library related to the inputMethod and
173: preeditType resources. The xterm(1) problem represents a security
174: vulnerability for any platform where xterm is installed setuid-root
175: (as is the case for all OpenBSD platforms). The Xaw problem represents
176: a security vulnerability for any setuid-root program that uses the Xaw
177: library (including xterm). Patch1 from XFree86 3.3.2 corrects
178: these problems.
