1.68 deraadt 16: <h2><font color=#0000e0>
17: This is the OpenBSD 2.2 release errata & patch list:
18: </font></h2>
19:
1.25 deraadt 20: <ul>
1.43 deraadt 21: <a name=all></a>
1.67 deraadt 22: <li><h3><font color=#e00000>All architectures</font></h3>
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
64: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.
65: <p>
1.72 deraadt 66: <a name=mmap></a>
67: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
68: If you rely on the system securelevels as described in init(8), you
69: will want this fix. A bug in the vm system permits a file descriptor
70: opened read-only on a device, to later on be mmap(2)'d read-write, and
71: then modified. This does not result in a security hole by itself, but
72: it does violate the safety semantics which securelevels are supposed to
1.78 deraadt 73: provide. If a user manages to gain kmem group permissions, using this
74: problem they can then gain root trivially.
1.72 deraadt 75: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
1.79 ! deraadt 76: A kernel patch is available which corrects this behaviour (this is
! 77: revision 2 of this patch)</a>.
1.72 deraadt 78: <p>
79: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
80: Building an object tree from a read-only source tree (such as off a CDROM)
81: may fail under certain circumstances (e.g. when creating a symlink on sparc
82: whose target name is exactly 33 characters). As a workaround you have to
83: either provide the source tree read/write, or install a newer version of
84: /usr/bin/readlink.
85: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
86: A replacement source file exists</a>.

1.76 deraadt 92: <a name=f00f></a>
1.72 deraadt 93: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
94: The Intel P5 F00F bug was discovered after the CDR's had already been
1.39 deraadt 95: sent to the manufacturer. This problem permits any user who has an account
96: to lock your machine up using a 4-line program. The problem only affects
97: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
98: nor are processors by other manufacturers).
1.44 deraadt 99: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/f00f.patch>
1.39 deraadt 100: A kernel source-code patch is available</a>.
101: <p>
1.72 deraadt 102: <li><font color=#009000><strong>FUNCTIONALITY FIX</strong></font><br>
103: Some Linux binaries will execute in SVR4 emulation mode, which is
1.33 deraadt 104: definately a problem for people who need Linux emulation to work correctly.
1.39 deraadt 105: To solve this mis-identification problem,
1.32 deraadt 106: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/compat_linux.patch>
1.72 deraadt 107: a patch file is provided</a>.
1.39 deraadt 108: <p>
1.72 deraadt 109: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
110: APM can crash on machines without it.

113: <p>
1.72 deraadt 114: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
115: A few people are running into this problem, particularily if they had some
1.39 deraadt 116: other *BSD operating system on their machine before trying OpenBSD: if after
117: installation onto an IDE-based machine, the kernel fails to mount the root
118: partition because it thinks that it should be opening sd0 (0x400), this means
119: you have incorrectly setup your disklabel for the IDE drive -- the disklabel
120: is indicating that the drive is SCSI.
121: To repair this, use the floppy to run "disklabel -E wd0", then using the
122: "edit" command ensure the type field is set to "ST506".

1.72 deraadt 128: <li><font color=#009000><strong>NEW SOFTWARE</strong></font><br>
129: Unfortunately, X11 binaries for the mac68k did not manage to make it onto the
1.69 deraadt 130: CDROM. However, X11 for the mac68k is immediately available from
1.46 gene 131: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz">
132: ftp://ftp.OpenBSD.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz</a>. Please

134: and setting up X.
1.39 deraadt 135: <p>
1.72 deraadt 136: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
137: As shipped on the CDROM, both the
138: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/bsd-generic.tar.gz">
139: generic kernel</a>
140: and the

1.72 deraadt 142: genericsbc kernel</a>
143: extract themselves into the wrong place in the filesystem.
1.70 gene 144: Both <strong>should</strong> extract a kernel named <tt>/bsd</tt>, but they extract
145: the kernel into <tt>/usr/src/sys/arch/mac68k/compile</tt> instead.
146: <p>
1.74 deraadt 147: This has been fixed on the ftp release of <a href=22.html>OpenBSD 2.2</a>, and
1.71 gene 148: fresh kernels are available from <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k">
149: ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/</a>. If at all possible,
150: installing these kernels is recommended.
151: <p>
152: A number of possible workarounds exist if you don't have easy access to ftp
153: the updated kernels. The simplest of these is to use a
1.70 gene 154: MacOS program to uncompress and untar the kernel aad use the Installer's
155: mini-shell to "cpin" the kernel. Alternately, you could install the kernel
156: with the Installer and use the mini-shell to move the binary from <tt>/usr/src/...</tt> to <tt>/bsd</tt>.
