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

58: <a name=chpass></a>
59: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
60: Chpass(1) has a file descriptor leak which allows an

80: As shipped, unionfs had some serious problems.
81: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/unionfs.patch>
82: A patch is available to solve this</a>.
83: <p>
84: <a name=fdalloc></a>
85: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
86: Some non-allocated file descriptors have implied uses according to
87: system libraries, and hence setuid and setgid processes should not
88: be executed with these descriptors unallocated. A patch which forces
89: setuid and setgid processes to have some descriptors in fd slots
90: 0, 1, and 2 is
91: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/fdalloc.patch>
92: available here.</a>
93: <p>
94: <a name=xlib></a>
95: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.3 deraadt 96: A benign looking buffer overflow in the resolver routines was re-introduced
97: accidentally. The previously fixed behaviour is more correct. A patch
98: to fix this is
99: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/resolver.patch>
100: available here.</a>
101: <p>
102: <a name=xlib></a>
103: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.1 deraadt 104: Vulnerabilities have been found in the X11, Xt, Xaw and Xmu
105: libraries. These affect xterm and all other setuid-root programs that
106: use these libraries. The problems are associated with buffer overflows
107: in code that processes user-supplied data. The Xt library problems
108: include those fixed in TOG's recent public patch 3 for X11R6.3. All
109: releases of XFree86 up to and including 3.3.2 patch 1 and the version
110: distributed with OpenBSD are vulnerable to some or all of these
111: problems.
112: These problems are fixed in XFree86 patch 2.
113: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/XFree86-3.3.2.2.patch>
114: The 2nd source patch</a> for these problems, specifically adapted to the
115: OpenBSD 2.3 X11 tree, is available now.
116: <p>
117: <a name=kill></a>
118: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
119: The kill(2) system call previously would permit a large set of signals to
120: be delivered to setuid or setgid processes. If such processes were using
121: those signals in dubious ways, this could have resulted in security
122: problems of various kinds.
123: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/kill.patch>
124: The fourth revision of a source code patch which solves the problem is
125: available.</a>
126: <p>
127: <a name=immutable></a>
128: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
129: A possible new security problem exists if you rely on securelevels and
130: immutable or append-only files or character devices. The fix does not
131: permit mmap'ing of immutable or append-only files which are otherwise
132: writeable, as the VM system will bypass the meaning of the file flags
133: when writes happen to the file.
134: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/immutable.patch>
135: A source code patch exists which remedies this problem.</a>
136: <p>
137: <a name=ipsec></a>
138: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
139: If IPSEC communication is attempted by starting photurisd(8) (which is
140: disabled by default), a system crash may be evoked from remote if
141: an attacker uses some classes of invalid packets.
142: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/ipsec.patch>
143: A source code patch exists which remedies this problem.</a>
144: <p>
145: <a name=xterm-xaw></a>
146: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
147: As stated in CERT advisory VB-98.04, there are buffer
148: overrun problems in <strong>xterm</strong> related to the input-Method,
149: preeditType, and *Keymap resources. Additional buffer overruns exist in
150: the <strong>Xaw</strong> library related to the inputMethod and
151: preeditType resources. The xterm(1) problem represents a security
152: vulnerability for any platform where xterm is installed setuid-root
153: (as is the case for all OpenBSD platforms). The Xaw problem represents
154: a security vulnerability for any setuid-root program that uses the Xaw
155: library (including xterm). Patch1 from XFree86 3.3.2 corrects
156: these problems.
157: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/xterm-xaw.patch>
158: We provide a version of this patch file specifically for the OpenBSD 2.3 tree</a>.
159: We also provide tar files which replace the xterm(1) binary and the libXaw
160: libraries on your system. These are expected to be extracted in
161: <strong>/usr/X11R6</strong> using the command
162: <strong>"tar xvfpz Xawfix.tgz"</strong>.

180: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
181: The pctr(4) driver has bugs that permit any user to crash the machine,
182: if the CPU is not an Intel CPU. This problem has been properly fixed
183: since, but fixes are hard to apply to the 2.2 or 2.3 releases. To avoid
184: the problem, recompile your kernel without the pctr(4) device driver.

186: <li><font color=#009000><strong>CORRUPTED FILE</strong></font><br>

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