1.87 deraadt 24: <a name=named></a>
25: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
26: A vulnerability exists when (and only when) /etc/named.conf has the
1.88 ! deraadt 27: <strong>fake-iquery</strong> option enabled.
1.87 deraadt 28: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/named.patch>
29: A patch is available which corrects this behaviour</a>.
30: <p>
31: <a name=ping></a>
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
1.88 ! deraadt 35: ping. Preliminary investigation makes it look the worst attack
! 36: possible is to make ping crash, but one never knows...
1.87 deraadt 37: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/ping.patch>
38: A patch is available which corrects this behaviour</a>.
39: <p>
1.72 deraadt 40: <a name=sourceroute></a>
41: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
42: If the sysctl variable <strong>net.inet.ip.forwarding</strong> is
43: enabled (value 1), but the variable <strong>net.inet.ip.sourceroute</strong>
1.73 deraadt 44: is disabled (value 0), the kernel will block source routed packets from
45: going through, but will still accept source routing packets destined for
1.72 deraadt 46: itself. Our fix changes the <strong>net.inet.ip.sourceroute</strong>
1.77 deraadt 47: variable semantics to mean that all source routed packets should
1.73 deraadt 48: be blocked completely.
1.72 deraadt 49: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/sourceroute.patch>
50: A kernel patch is provided</a>.
1.39 deraadt 51: <p>
1.62 deraadt 52: <a name=ruserok></a>
1.72 deraadt 53: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.61 deraadt 54: A combination localhost+remote host security problem exists if a
55: local user running a setuid binary causes a non-existant root .rhosts
56: file to be created via a symbolic link with a specific kind of corefile,
57: and then subsequently uses rsh/rlogin to enter the machine from remote.
58: A similar exploit might also be possible using sshd which lacks any code
59: for checking for deviations from the expected format in the .rhosts or
60: .shosts files, but we have not confirmed this yet. The following two
61: fixes are recommended:
62: <p>
63: <ul>
64: <li>
65: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/nosuidcoredump.patch>
1.72 deraadt 66: (1) A kernel patch which adds a new sysctl option which permits the
67: administrator to decide whether setuid corefiles should be written or not</a>.
1.61 deraadt 68: <p>
69: <li><a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rcmd.patch>
1.74 deraadt 70: (2) Replaces the libc ruserok() function with a more paranoid
71: version which detects bogus looking .rhosts files better.</a>
1.61 deraadt 72: </ul>
73: <p>
1.74 deraadt 74: If the
75: first patch is used to stop setuid coredumps, then the second patch is
76: not as important.
1.61 deraadt 77: This problem is fixed much better in OpenBSD-current, where the kernel's
78: symbolic link handling has been improved such that coredumping will not
79: create a file on the other side of a symbolic link. Such a patch is not
1.81 deraadt 80: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>
81: The problem with the ruserok() function appears to also exist in
82: ssh 1.2.21 and previous (the ssh people have been alerted).
1.61 deraadt 83: <p>
1.72 deraadt 84: <a name=mmap></a>
85: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
1.80 deraadt 86: A bug in the vm system permits a file descriptor opened read-only on a
87: device, to later on be mmap(2)'d read-write, and then modified. This
88: does not result in a security hole by itself, but it does violate the
89: safety semantics which securelevels are supposed to provide. If a user
90: manages to gain kmem group permissions, using this problem they can then
91: gain root trivially and/or turn securelevels off.
1.72 deraadt 92: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
1.79 deraadt 93: A kernel patch is available which corrects this behaviour (this is
1.83 deraadt 94: revision 3 of this patch)</a>.
1.72 deraadt 95: <p>
96: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
97: Building an object tree from a read-only source tree (such as off a CDROM)
98: may fail under certain circumstances (e.g. when creating a symlink on sparc
99: whose target name is exactly 33 characters). As a workaround you have to
100: either provide the source tree read/write, or install a newer version of
101: /usr/bin/readlink.
102: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
103: A replacement source file exists</a>.
104: <p>
1.85 deraadt 105: <a name=mountd></a>
1.84 deraadt 106: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
107: If a line in /etc/exports which contains hostnames results in an empty
108: list because none of the supplied hostnames is known, mountd(8) will
109: accidentally export the filesystem to the world.
110: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/mountd.patch>
111: A patch is available which corrects this behaviour</a>.
112: <p>
1.86 millert 113: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
114: Setting the MSG_EOR flag on a tcp packet in the send(2) family of
115: system calls could cause a kernel panic.
116: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/send.patch>
117: A patch</a> to return EINVAL in this case is available.

1.76 deraadt 123: <a name=f00f></a>
1.72 deraadt 124: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
125: The Intel P5 F00F bug was discovered after the CDR's had already been
1.39 deraadt 126: sent to the manufacturer. This problem permits any user who has an account
127: to lock your machine up using a 4-line program. The problem only affects
128: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
129: nor are processors by other manufacturers).
1.44 deraadt 130: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/f00f.patch>
1.39 deraadt 131: A kernel source-code patch is available</a>.
132: <p>
1.72 deraadt 133: <li><font color=#009000><strong>FUNCTIONALITY FIX</strong></font><br>
134: Some Linux binaries will execute in SVR4 emulation mode, which is
1.33 deraadt 135: definately a problem for people who need Linux emulation to work correctly.
1.39 deraadt 136: To solve this mis-identification problem,
1.32 deraadt 137: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/compat_linux.patch>

1.39 deraadt 139: <p>
1.72 deraadt 140: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
141: APM can crash on machines without it.
1.45 deraadt 142: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/apm.patch>

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

160: Unfortunately, X11 binaries for the mac68k did not manage to make it onto the
1.69 deraadt 161: CDROM. However, X11 for the mac68k is immediately available from
1.46 gene 162: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz">

168: As shipped on the CDROM, both the

170: generic kernel</a>

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