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

1.1 deraadt 139: The kill(2) system call previously would permit a large set of signals to
140: be delivered to setuid or setgid processes. If such processes were using
141: those signals in dubious ways, this could have resulted in security
142: problems of various kinds.

1.1 deraadt 149: A possible new security problem exists if you rely on securelevels and
150: immutable or append-only files or character devices. The fix does not
151: permit mmap'ing of immutable or append-only files which are otherwise
1.17 pvalchev 152: writable, as the VM system will bypass the meaning of the file flags

1.28 naddy 166: <li><font color="#009000"><strong>SECURITY FIX</strong></font><br>
1.1 deraadt 167: As stated in CERT advisory VB-98.04, there are buffer
168: overrun problems in <strong>xterm</strong> related to the input-Method,
169: preeditType, and *Keymap resources. Additional buffer overruns exist in
170: the <strong>Xaw</strong> library related to the inputMethod and
171: preeditType resources. The xterm(1) problem represents a security
172: vulnerability for any platform where xterm is installed setuid-root
173: (as is the case for all OpenBSD platforms). The Xaw problem represents
174: a security vulnerability for any setuid-root program that uses the Xaw
175: library (including xterm). Patch1 from XFree86 3.3.2 corrects
176: these problems.
