! 26: A vulnerability exists when (and only when) /etc/named.conf has the
! 27: <strong>fake-iquery</strong> option enabled.

! 32: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 33: A vulnerability exists in ping(8); if the -R option is used to record
! 34: routes, an attacker can spoof a reply packet that will overflow inside
! 35: ping.

1.72 deraadt 39: <a name=sourceroute></a>
40: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
41: If the sysctl variable <strong>net.inet.ip.forwarding</strong> is
42: enabled (value 1), but the variable <strong>net.inet.ip.sourceroute</strong>
1.73 deraadt 43: is disabled (value 0), the kernel will block source routed packets from
44: going through, but will still accept source routing packets destined for
1.72 deraadt 45: itself. Our fix changes the <strong>net.inet.ip.sourceroute</strong>
1.77 deraadt 46: variable semantics to mean that all source routed packets should
1.73 deraadt 47: be blocked completely.
1.72 deraadt 48: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/sourceroute.patch>
49: A kernel patch is provided</a>.

1.62 deraadt 51: <a name=ruserok></a>
1.72 deraadt 52: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.61 deraadt 53: A combination localhost+remote host security problem exists if a
54: local user running a setuid binary causes a non-existant root .rhosts
55: file to be created via a symbolic link with a specific kind of corefile,
56: and then subsequently uses rsh/rlogin to enter the machine from remote.
57: A similar exploit might also be possible using sshd which lacks any code
58: for checking for deviations from the expected format in the .rhosts or
59: .shosts files, but we have not confirmed this yet. The following two
60: fixes are recommended:
61: <p>
62: <ul>
63: <li>
64: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/nosuidcoredump.patch>
1.72 deraadt 65: (1) A kernel patch which adds a new sysctl option which permits the
66: administrator to decide whether setuid corefiles should be written or not</a>.
1.61 deraadt 67: <p>
68: <li><a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rcmd.patch>
1.74 deraadt 69: (2) Replaces the libc ruserok() function with a more paranoid
70: version which detects bogus looking .rhosts files better.</a>
1.61 deraadt 71: </ul>
72: <p>
1.74 deraadt 73: If the
74: first patch is used to stop setuid coredumps, then the second patch is
75: not as important.
1.61 deraadt 76: This problem is fixed much better in OpenBSD-current, where the kernel's
77: symbolic link handling has been improved such that coredumping will not
78: create a file on the other side of a symbolic link. Such a patch is not
1.81 deraadt 79: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>
80: The problem with the ruserok() function appears to also exist in
81: ssh 1.2.21 and previous (the ssh people have been alerted).
1.61 deraadt 82: <p>
1.72 deraadt 83: <a name=mmap></a>
84: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
1.80 deraadt 85: A bug in the vm system permits a file descriptor opened read-only on a
86: device, to later on be mmap(2)'d read-write, and then modified. This
87: does not result in a security hole by itself, but it does violate the
88: safety semantics which securelevels are supposed to provide. If a user
89: manages to gain kmem group permissions, using this problem they can then
90: gain root trivially and/or turn securelevels off.
1.72 deraadt 91: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
1.79 deraadt 92: A kernel patch is available which corrects this behaviour (this is
1.83 deraadt 93: revision 3 of this patch)</a>.
1.72 deraadt 94: <p>
95: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
96: Building an object tree from a read-only source tree (such as off a CDROM)
97: may fail under certain circumstances (e.g. when creating a symlink on sparc
98: whose target name is exactly 33 characters). As a workaround you have to
99: either provide the source tree read/write, or install a newer version of
100: /usr/bin/readlink.
101: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
102: A replacement source file exists</a>.
103: <p>
1.85 deraadt 104: <a name=mountd></a>
1.84 deraadt 105: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
106: If a line in /etc/exports which contains hostnames results in an empty
107: list because none of the supplied hostnames is known, mountd(8) will
108: accidentally export the filesystem to the world.
109: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/mountd.patch>
110: A patch is available which corrects this behaviour</a>.
111: <p>
1.86 millert 112: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
113: Setting the MSG_EOR flag on a tcp packet in the send(2) family of
114: system calls could cause a kernel panic.
115: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/send.patch>
116: A patch</a> to return EINVAL in this case is available.

1.72 deraadt 123: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
124: The Intel P5 F00F bug was discovered after the CDR's had already been
1.39 deraadt 125: sent to the manufacturer. This problem permits any user who has an account
126: to lock your machine up using a 4-line program. The problem only affects
127: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
128: nor are processors by other manufacturers).
1.44 deraadt 129: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/f00f.patch>

131: <p>
1.72 deraadt 132: <li><font color=#009000><strong>FUNCTIONALITY FIX</strong></font><br>
133: Some Linux binaries will execute in SVR4 emulation mode, which is
1.33 deraadt 134: definately a problem for people who need Linux emulation to work correctly.
1.39 deraadt 135: To solve this mis-identification problem,
1.32 deraadt 136: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/compat_linux.patch>

1.39 deraadt 138: <p>
1.72 deraadt 139: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
140: APM can crash on machines without it.

143: <p>
1.72 deraadt 144: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
145: A few people are running into this problem, particularily if they had some
1.39 deraadt 146: other *BSD operating system on their machine before trying OpenBSD: if after
147: installation onto an IDE-based machine, the kernel fails to mount the root
148: partition because it thinks that it should be opening sd0 (0x400), this means
149: you have incorrectly setup your disklabel for the IDE drive -- the disklabel
150: is indicating that the drive is SCSI.
151: To repair this, use the floppy to run "disklabel -E wd0", then using the
152: "edit" command ensure the type field is set to "ST506".

159: Unfortunately, X11 binaries for the mac68k did not manage to make it onto the
1.69 deraadt 160: CDROM. However, X11 for the mac68k is immediately available from
1.46 gene 161: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz">

167: As shipped on the CDROM, both the

1.70 gene 174: Both <strong>should</strong> extract a kernel named <tt>/bsd</tt>, but they extract
175: the kernel into <tt>/usr/src/sys/arch/mac68k/compile</tt> instead.
176: <p>
1.74 deraadt 177: This has been fixed on the ftp release of <a href=22.html>OpenBSD 2.2</a>, and
1.71 gene 178: fresh kernels are available from <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k">
179: ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/</a>. If at all possible,
180: installing these kernels is recommended.
181: <p>
182: A number of possible workarounds exist if you don't have easy access to ftp
183: the updated kernels. The simplest of these is to use a
1.70 gene 184: MacOS program to uncompress and untar the kernel aad use the Installer's
185: mini-shell to "cpin" the kernel. Alternately, you could install the kernel
186: with the Installer and use the mini-shell to move the binary from <tt>/usr/src/...</tt> to <tt>/bsd</tt>.
