1.25 deraadt 20: <ul>

1.25 deraadt 23: <ul>
1.72 deraadt 24: <a name=sourceroute></a>
25: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
26: If the sysctl variable <strong>net.inet.ip.forwarding</strong> is
27: enabled (value 1), but the variable <strong>net.inet.ip.sourceroute</strong>
1.73 deraadt 28: is disabled (value 0), the kernel will block source routed packets from
29: going through, but will still accept source routing packets destined for
1.72 deraadt 30: itself. Our fix changes the <strong>net.inet.ip.sourceroute</strong>
1.77 deraadt 31: variable semantics to mean that all source routed packets should
1.73 deraadt 32: be blocked completely.
1.72 deraadt 33: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/sourceroute.patch>
34: A kernel patch is provided</a>.
1.39 deraadt 35: <p>
1.62 deraadt 36: <a name=ruserok></a>
1.72 deraadt 37: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
1.61 deraadt 38: A combination localhost+remote host security problem exists if a
39: local user running a setuid binary causes a non-existant root .rhosts
40: file to be created via a symbolic link with a specific kind of corefile,
41: and then subsequently uses rsh/rlogin to enter the machine from remote.
42: A similar exploit might also be possible using sshd which lacks any code
43: for checking for deviations from the expected format in the .rhosts or
44: .shosts files, but we have not confirmed this yet. The following two
45: fixes are recommended:
46: <p>
47: <ul>
48: <li>
49: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/nosuidcoredump.patch>
1.72 deraadt 50: (1) A kernel patch which adds a new sysctl option which permits the
51: administrator to decide whether setuid corefiles should be written or not</a>.
1.61 deraadt 52: <p>
53: <li><a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rcmd.patch>
1.74 deraadt 54: (2) Replaces the libc ruserok() function with a more paranoid
55: version which detects bogus looking .rhosts files better.</a>
1.61 deraadt 56: </ul>
57: <p>
1.74 deraadt 58: If the
59: first patch is used to stop setuid coredumps, then the second patch is
60: not as important.
1.61 deraadt 61: This problem is fixed much better in OpenBSD-current, where the kernel's
62: symbolic link handling has been improved such that coredumping will not
63: create a file on the other side of a symbolic link. Such a patch is not
1.81 deraadt 64: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>
65: The problem with the ruserok() function appears to also exist in
66: ssh 1.2.21 and previous (the ssh people have been alerted).
1.61 deraadt 67: <p>
1.72 deraadt 68: <a name=mmap></a>
69: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
1.80 deraadt 70: A bug in the vm system permits a file descriptor opened read-only on a
71: device, to later on be mmap(2)'d read-write, and then modified. This
72: does not result in a security hole by itself, but it does violate the
73: safety semantics which securelevels are supposed to provide. If a user
74: manages to gain kmem group permissions, using this problem they can then
75: gain root trivially and/or turn securelevels off.
1.72 deraadt 76: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
1.79 deraadt 77: A kernel patch is available which corrects this behaviour (this is
1.83 deraadt 78: revision 3 of this patch)</a>.
1.72 deraadt 79: <p>
80: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
81: Building an object tree from a read-only source tree (such as off a CDROM)
82: may fail under certain circumstances (e.g. when creating a symlink on sparc
83: whose target name is exactly 33 characters). As a workaround you have to
84: either provide the source tree read/write, or install a newer version of
85: /usr/bin/readlink.
86: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
87: A replacement source file exists</a>.
88: <p>
1.84 ! deraadt 89: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 90: If a line in /etc/exports which contains hostnames results in an empty
! 91: list because none of the supplied hostnames is known, mountd(8) will
! 92: accidentally export the filesystem to the world.
! 93: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/mountd.patch>

1.72 deraadt 101: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
102: The Intel P5 F00F bug was discovered after the CDR's had already been
1.39 deraadt 103: sent to the manufacturer. This problem permits any user who has an account
104: to lock your machine up using a 4-line program. The problem only affects
105: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
106: nor are processors by other manufacturers).

111: Some Linux binaries will execute in SVR4 emulation mode, which is
1.33 deraadt 112: definately a problem for people who need Linux emulation to work correctly.
1.39 deraadt 113: To solve this mis-identification problem,

1.72 deraadt 122: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
123: A few people are running into this problem, particularily if they had some
1.39 deraadt 124: other *BSD operating system on their machine before trying OpenBSD: if after
125: installation onto an IDE-based machine, the kernel fails to mount the root
126: partition because it thinks that it should be opening sd0 (0x400), this means
127: you have incorrectly setup your disklabel for the IDE drive -- the disklabel
128: is indicating that the drive is SCSI.
129: To repair this, use the floppy to run "disklabel -E wd0", then using the
130: "edit" command ensure the type field is set to "ST506".

145: As shipped on the CDROM, both the

1.70 gene 152: Both <strong>should</strong> extract a kernel named <tt>/bsd</tt>, but they extract
153: the kernel into <tt>/usr/src/sys/arch/mac68k/compile</tt> instead.
154: <p>
1.74 deraadt 155: This has been fixed on the ftp release of <a href=22.html>OpenBSD 2.2</a>, and
1.71 gene 156: fresh kernels are available from <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k">
157: ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/</a>. If at all possible,
158: installing these kernels is recommended.
159: <p>
160: A number of possible workarounds exist if you don't have easy access to ftp
161: the updated kernels. The simplest of these is to use a
1.70 gene 162: MacOS program to uncompress and untar the kernel aad use the Installer's
163: mini-shell to "cpin" the kernel. Alternately, you could install the kernel
164: with the Installer and use the mini-shell to move the binary from <tt>/usr/src/...</tt> to <tt>/bsd</tt>.
