62: Some ATAPI cdroms which do not support the full mandatory command set,
63: (e.g. ATAPI_READ_CD_CAPACITY) do not work with the acd(4) driver.
64: A patch is

67: <p>
68: <a name=chpass></a>
69: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>

78: kernel panic. This is the third revision of this patch.

87: <p>

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

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

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

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