91: As shipped, unionfs had some serious problems.
92: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/unionfs.patch>
93: A patch is available to solve this</a>.
94: <p>
95: <a name=fdalloc></a>
96: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
97: Some non-allocated file descriptors have implied uses according to
98: system libraries, and hence setuid and setgid processes should not
99: be executed with these descriptors unallocated. A patch which forces
100: setuid and setgid processes to have some descriptors in fd slots
101: 0, 1, and 2 is
102: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/fdalloc.patch>
103: available here.</a>

105: <a name=xlib></a>
106: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.3 deraadt 107: A benign looking buffer overflow in the resolver routines was re-introduced
108: accidentally. The previously fixed behaviour is more correct. A patch
109: to fix this is
110: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/resolver.patch>
111: available here.</a>
112: <p>
113: <a name=xlib></a>
114: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.1 deraadt 115: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
116: libraries. These affect xterm and all other setuid-root programs that
117: use these libraries. The problems are associated with buffer overflows
118: in code that processes user-supplied data. The Xt library problems
119: include those fixed in TOG's recent public patch 3 for X11R6.3. All
120: releases of XFree86 up to and including 3.3.2 patch 1 and the version
121: distributed with OpenBSD are vulnerable to some or all of these
122: problems.
123: These problems are fixed in XFree86 patch 2.
124: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/XFree86-3.3.2.2.patch>
125: The 2nd source patch</a> for these problems, specifically adapted to the
126: OpenBSD 2.3 X11 tree, is available now.
127: <p>
128: <a name=kill></a>
129: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
130: The kill(2) system call previously would permit a large set of signals to
131: be delivered to setuid or setgid processes. If such processes were using
132: those signals in dubious ways, this could have resulted in security
133: problems of various kinds.
134: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/kill.patch>
135: The fourth revision of a source code patch which solves the problem is
136: available.</a>
137: <p>
138: <a name=immutable></a>
139: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
140: A possible new security problem exists if you rely on securelevels and
141: immutable or append-only files or character devices. The fix does not
142: permit mmap'ing of immutable or append-only files which are otherwise
143: writeable, as the VM system will bypass the meaning of the file flags
144: when writes happen to the file.
145: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/immutable.patch>
146: A source code patch exists which remedies this problem.</a>
147: <p>
148: <a name=ipsec></a>
149: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
150: If IPSEC communication is attempted by starting photurisd(8) (which is
151: disabled by default), a system crash may be evoked from remote if
152: an attacker uses some classes of invalid packets.
153: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/ipsec.patch>
154: A source code patch exists which remedies this problem.</a>
155: <p>
156: <a name=xterm-xaw></a>
157: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
158: As stated in CERT advisory VB-98.04, there are buffer
159: overrun problems in <strong>xterm</strong> related to the input-Method,
160: preeditType, and *Keymap resources. Additional buffer overruns exist in
161: the <strong>Xaw</strong> library related to the inputMethod and
162: preeditType resources. The xterm(1) problem represents a security
163: vulnerability for any platform where xterm is installed setuid-root
164: (as is the case for all OpenBSD platforms). The Xaw problem represents
165: a security vulnerability for any setuid-root program that uses the Xaw
166: library (including xterm). Patch1 from XFree86 3.3.2 corrects
167: these problems.
168: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/xterm-xaw.patch>
169: We provide a version of this patch file specifically for the OpenBSD 2.3 tree</a>.
170: We also provide tar files which replace the xterm(1) binary and the libXaw
171: libraries on your system. These are expected to be extracted in
172: <strong>/usr/X11R6</strong> using the command
173: <strong>"tar xvfpz Xawfix.tgz"</strong>.

190: <a name=pctr></a>
191: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
192: The pctr(4) driver has bugs that permit any user to crash the machine,
193: if the CPU is not an Intel CPU. This problem has been properly fixed
194: since, but fixes are hard to apply to the 2.2 or 2.3 releases. To avoid
195: the problem, recompile your kernel without the pctr(4) device driver.
196: <p>
197: <li><font color=#009000><strong>CORRUPTED FILE</strong></font><br>
198: The CD version of the precompiled ghostscript package is corrupted and
199: not installable. The correct file can be retrieved by FTP from:

202: Its checksums (obtained with <i>cksum(1)</i>, <i>md5(1)</i> and
203: <i>sha1(1)</i> respectively) are:

210: <a name=pcvt></a>
211: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
212: The pcvt(4) console driver has a bug that can cause some keyboard
213: controllers to lock up when a key is pressed that toggles the status
214: of a keyboard LED (scroll lock, caps lock, etc). The problem is
215: generally intermittent and the keyboard can be "unlocked" by unplugging
216: and plugging it back in.

246: The AmigaOS patch
