40: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
41: A remotely exploitable problem exists in bootpd(8). bootpd is disabled
42: by default, but some people may actually be using it.
1.6 deraadt 43: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/bootpd.patch>
1.7 millert 44: A source code patch exists which remedies this problem</a>, this is the

1.1 deraadt 53: <a name=atapi></a>
54: <li><font color=#009000><strong>HARDWARE SUPPORT</strong></font><br>
55: Some ATAPI cdroms which do not support the full mandatory command set,
56: (e.g. ATAPI_READ_CD_CAPACITY) do not work with the acd(4) driver.
57: A patch is
58: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/acd.patch>
59: available here.</a>
60: <p>
61: <a name=chpass></a>
62: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
63: Chpass(1) has a file descriptor leak which allows an
64: attacker to modify /etc/master.passwd.
65: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/chpass.patch>
66: A source code patch exists which remedies this problem.</a>

69: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
70: Calling readv(2) with iov_len < 0 or > INT_MAX would result in a
71: kernel panic. This is the third revision of this patch.
72: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/resid.patch>
73: A source code patch exists which remedies this problem.</a>
74: <p>

76: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
77: Inetd had a file descriptor leak. A patch is

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

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

194: Its checksums (obtained with <i>cksum(1)</i>, <i>md5(1)</i> and
195: <i>sha1(1)</i> respectively) are:
196: <ul>

202: <a name=pcvt></a>
203: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
204: The pcvt(4) console driver has a bug that can cause some keyboard
205: controllers to lock up when a key is pressed that toggles the status
206: of a keyboard LED (scroll lock, caps lock, etc). The problem is
207: generally intermittent and the keyboard can be "unlocked" by unplugging
208: and plugging it back in.
209: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/i386/pcvt.patch>

238: The AmigaOS patch
239: <a href="http://us.aminet.net/pub/aminet/util/sys/PoolMem.lha">PoolMem</a>
