1.5 matthieu 50: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.7 deraadt 51: If IPSEC communication is attempted by starting photurisd(8) (which is
1.8 deraadt 52: disabled by default), a system crash may be evoked from remote if
53: an attacker uses some classes of invalid packets.
1.7 deraadt 54: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.3/common/ipsec.patch>
55: A source code patch exists which remedies this problem.</a>

57: <a name=xterm-xaw></a>
1.7 deraadt 58: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.5 matthieu 59: As stated in CERT advisory VB-98.04, there are buffer
1.8 deraadt 60: overrun problems in <strong>xterm</strong> related to the input-Method,
61: preeditType, and *Keymap resources. Additional buffer overruns exist in
62: the <strong>Xaw</strong> library related to the inputMethod and
63: preeditType resources. The xterm(1) problem represents a security
64: vulnerability for any platform where xterm is installed setuid-root
65: (as is the case for all OpenBSD platforms). The Xaw problem represents
66: a security vulnerability for any setuid-root program that uses the Xaw
67: library (including xterm). Patch1 from XFree86 3.3.2 corrects
68: these problems.
1.5 matthieu 69: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/xterm-xaw.patch>
1.6 deraadt 70: We provide a version of this patch file specifically for the OpenBSD 2.2 tree</a>.

1.1 deraadt 72: <a name=rmjob></a>
73: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
74: An exploitable buffer mismanagement exists in a subroutine used by
75: lprm and lpd. The problem is exploitable by users on a particular
76: machine if there is an entry in <strong>/etc/printcap</strong> which
77: points at a remote printer.
78: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rmjob.patch>
79: A patch is available which corrects this behaviour</a>.
80: <p>
81: <a name=uucpd></a>
82: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
83: A DNS-based vulnerability exists when uucpd is used. By default uucpd
84: is not enabled in the OpenBSD releases, but some sites may have enabled it.
85: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/uucpd.patch>
86: A patch is available which corrects this behaviour</a>.
87: <p>
88: <a name=named></a>
89: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
90: A vulnerability exists when (and only when) /etc/named.conf has the
91: <strong>fake-iquery</strong> option enabled.
92: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/named.patch>
93: A patch is available which corrects this behaviour</a>.
94: <p>
95: <a name=ping></a>
96: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
97: A vulnerability exists in ping(8); if the -R option is used to record
98: routes, an attacker can spoof a reply packet that will overflow inside
99: ping. Preliminary investigation makes it look the worst attack
100: possible is to make ping crash, but one never knows...
101: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/ping.patch>
102: A patch is available which corrects this behaviour</a>.
103: <p>
104: <a name=sourceroute></a>
1.23 jufi 105: <li><strong><font color=#009000>SECURITY FIX</font></strong><br>
1.1 deraadt 106: If the sysctl variable <strong>net.inet.ip.forwarding</strong> is
107: enabled (value 1), but the variable <strong>net.inet.ip.sourceroute</strong>
108: is disabled (value 0), the kernel will block source routed packets from
109: going through, but will still accept source routing packets destined for
110: itself. Our fix changes the <strong>net.inet.ip.sourceroute</strong>
111: variable semantics to mean that all source routed packets should
112: be blocked completely.
113: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/sourceroute.patch>
114: A kernel patch is provided</a>.
115: <p>
116: <a name=ruserok></a>
117: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
118: A combination localhost+remote host security problem exists if a
1.26 jsyn 119: local user running a setuid binary causes a non-existent root .rhosts
1.1 deraadt 120: file to be created via a symbolic link with a specific kind of corefile,
121: and then subsequently uses rsh/rlogin to enter the machine from remote.
122: A similar exploit might also be possible using sshd which lacks any code
123: for checking for deviations from the expected format in the .rhosts or
124: .shosts files, but we have not confirmed this yet. The following two
125: fixes are recommended:
126: <p>
127: <ul>
128: <li>
129: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/nosuidcoredump.patch>
130: (1) A kernel patch which adds a new sysctl option which permits the
131: administrator to decide whether setuid corefiles should be written or not</a>.
132: <p>
133: <li><a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rcmd.patch>
134: (2) Replaces the libc ruserok() function with a more paranoid
135: version which detects bogus looking .rhosts files better.</a>
136: </ul>
137: <p>
138: If the
139: first patch is used to stop setuid coredumps, then the second patch is
140: not as important.
141: This problem is fixed much better in OpenBSD-current, where the kernel's
142: symbolic link handling has been improved such that coredumping will not
143: create a file on the other side of a symbolic link. Such a patch is not
144: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>
145: The problem with the ruserok() function appears to also exist in
146: ssh 1.2.21 and previous (the ssh people have been alerted).
147: <p>
148: <a name=mmap></a>
1.23 jufi 149: <li><strong><font color=#009000>SECURITY FIX</font></strong><br>
1.1 deraadt 150: A bug in the vm system permits a file descriptor opened read-only on a
151: device, to later on be mmap(2)'d read-write, and then modified. This
152: does not result in a security hole by itself, but it does violate the
153: safety semantics which securelevels are supposed to provide. If a user
154: manages to gain kmem group permissions, using this problem they can then
155: gain root trivially and/or turn securelevels off.
156: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
157: A kernel patch is available which corrects this behaviour (this is
158: revision 3 of this patch)</a>.
159: <p>
160: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
161: Building an object tree from a read-only source tree (such as off a CDROM)
162: may fail under certain circumstances (e.g. when creating a symlink on sparc
163: whose target name is exactly 33 characters). As a workaround you have to
164: either provide the source tree read/write, or install a newer version of
165: /usr/bin/readlink.
166: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
167: A replacement source file exists</a>.
168: <p>
169: <a name=mountd></a>
170: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
171: If a line in /etc/exports which contains hostnames results in an empty
172: list because none of the supplied hostnames is known, mountd(8) will
173: accidentally export the filesystem to the world.
174: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/mountd.patch>
175: A patch is available which corrects this behaviour</a>.
176: <p>
177: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
178: Setting the MSG_EOR flag on a tcp packet in the send(2) family of
179: system calls could cause a kernel panic.
180: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/send.patch>
181: A patch</a> to return EINVAL in this case is available.

188: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
1.26 jsyn 189: The Intel P5 F00F bug was discovered after the CDRs had already been
1.1 deraadt 190: sent to the manufacturer. This problem permits any user who has an account
191: to lock your machine up using a 4-line program. The problem only affects
192: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
193: nor are processors by other manufacturers).
194: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/f00f.patch>
195: A kernel source-code patch is available</a>.
196: <p>
197: <li><font color=#009000><strong>FUNCTIONALITY FIX</strong></font><br>
198: Some Linux binaries will execute in SVR4 emulation mode, which is
1.12 aaron 199: definitely a problem for people who need Linux emulation to work correctly.
1.1 deraadt 200: To solve this mis-identification problem,
201: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/compat_linux.patch>
202: a patch file is provided</a>.

205: APM can crash on machines without it.

209: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
1.25 pvalchev 210: A few people are running into this problem, particularly if they had some
1.1 deraadt 211: other *BSD operating system on their machine before trying OpenBSD: if after
212: installation onto an IDE-based machine, the kernel fails to mount the root
213: partition because it thinks that it should be opening sd0 (0x400), this means
214: you have incorrectly setup your disklabel for the IDE drive -- the disklabel
215: is indicating that the drive is SCSI.
216: To repair this, use the floppy to run "disklabel -E wd0", then using the
217: "edit" command ensure the type field is set to "ST506".

232: As shipped on the CDROM, both the
233: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/bsd-generic.tar.gz">
234: generic kernel</a>

238: extract themselves into the wrong place in the filesystem.
239: Both <strong>should</strong> extract a kernel named <tt>/bsd</tt>, but they extract
240: the kernel into <tt>/usr/src/sys/arch/mac68k/compile</tt> instead.
241: <p>
242: This has been fixed on the ftp release of <a href=22.html>OpenBSD 2.2</a>, and
243: fresh kernels are available from <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k">
244: ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/</a>. If at all possible,
245: installing these kernels is recommended.
246: <p>
247: A number of possible workarounds exist if you don't have easy access to ftp
248: the updated kernels. The simplest of these is to use a
249: MacOS program to uncompress and untar the kernel aad use the Installer's
250: mini-shell to "cpin" the kernel. Alternately, you could install the kernel
251: with the Installer and use the mini-shell to move the binary from <tt>/usr/src/...</tt> to <tt>/bsd</tt>.
