! 17: This is the OpenBSD 2.2 release errata & patch list:
! 18: </font></h2>
! 19:
! 20: <ul>
! 21: <a name=all></a>
! 22: <li><h3><font color=#e00000>All architectures</font></h3>
! 23: <ul>
! 24: <a name=rmjob></a>
! 25: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 26: An exploitable buffer mismanagement exists in a subroutine used by
! 27: lprm and lpd. The problem is exploitable by users on a particular
! 28: machine if there is an entry in <strong>/etc/printcap</strong> which
! 29: points at a remote printer.
! 30: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rmjob.patch>
! 31: A patch is available which corrects this behaviour</a>.
! 32: <p>
! 33: <a name=uucpd></a>
! 34: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 35: A DNS-based vulnerability exists when uucpd is used. By default uucpd
! 36: is not enabled in the OpenBSD releases, but some sites may have enabled it.
! 37: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/uucpd.patch>
! 38: A patch is available which corrects this behaviour</a>.
! 39: <p>
! 40: <a name=named></a>
! 41: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 42: A vulnerability exists when (and only when) /etc/named.conf has the
! 43: <strong>fake-iquery</strong> option enabled.
! 44: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/named.patch>
! 45: A patch is available which corrects this behaviour</a>.
! 46: <p>
! 47: <a name=ping></a>
! 48: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 49: A vulnerability exists in ping(8); if the -R option is used to record
! 50: routes, an attacker can spoof a reply packet that will overflow inside
! 51: ping. Preliminary investigation makes it look the worst attack
! 52: possible is to make ping crash, but one never knows...
! 53: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/ping.patch>
! 54: A patch is available which corrects this behaviour</a>.
! 55: <p>
! 56: <a name=sourceroute></a>
! 57: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
! 58: If the sysctl variable <strong>net.inet.ip.forwarding</strong> is
! 59: enabled (value 1), but the variable <strong>net.inet.ip.sourceroute</strong>
! 60: is disabled (value 0), the kernel will block source routed packets from
! 61: going through, but will still accept source routing packets destined for
! 62: itself. Our fix changes the <strong>net.inet.ip.sourceroute</strong>
! 63: variable semantics to mean that all source routed packets should
! 64: be blocked completely.
! 65: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/sourceroute.patch>
! 66: A kernel patch is provided</a>.
! 67: <p>
! 68: <a name=ruserok></a>
! 69: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 70: A combination localhost+remote host security problem exists if a
! 71: local user running a setuid binary causes a non-existant root .rhosts
! 72: file to be created via a symbolic link with a specific kind of corefile,
! 73: and then subsequently uses rsh/rlogin to enter the machine from remote.
! 74: A similar exploit might also be possible using sshd which lacks any code
! 75: for checking for deviations from the expected format in the .rhosts or
! 76: .shosts files, but we have not confirmed this yet. The following two
! 77: fixes are recommended:
! 78: <p>
! 79: <ul>
! 80: <li>
! 81: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/nosuidcoredump.patch>
! 82: (1) A kernel patch which adds a new sysctl option which permits the
! 83: administrator to decide whether setuid corefiles should be written or not</a>.
! 84: <p>
! 85: <li><a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/rcmd.patch>
! 86: (2) Replaces the libc ruserok() function with a more paranoid
! 87: version which detects bogus looking .rhosts files better.</a>
! 88: </ul>
! 89: <p>
! 90: If the
! 91: first patch is used to stop setuid coredumps, then the second patch is
! 92: not as important.
! 93: This problem is fixed much better in OpenBSD-current, where the kernel's
! 94: symbolic link handling has been improved such that coredumping will not
! 95: create a file on the other side of a symbolic link. Such a patch is not
! 96: possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.<p>
! 97: The problem with the ruserok() function appears to also exist in
! 98: ssh 1.2.21 and previous (the ssh people have been alerted).
! 99: <p>
! 100: <a name=mmap></a>
! 101: <li><strong><font color=#009000>SECURITY FIX</strong></font><br>
! 102: A bug in the vm system permits a file descriptor opened read-only on a
! 103: device, to later on be mmap(2)'d read-write, and then modified. This
! 104: does not result in a security hole by itself, but it does violate the
! 105: safety semantics which securelevels are supposed to provide. If a user
! 106: manages to gain kmem group permissions, using this problem they can then
! 107: gain root trivially and/or turn securelevels off.
! 108: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/vm_mmap.patch>
! 109: A kernel patch is available which corrects this behaviour (this is
! 110: revision 3 of this patch)</a>.
! 111: <p>
! 112: <li><font color=#009000><strong>BUILD PROCESS FIX</strong></font><br>
! 113: Building an object tree from a read-only source tree (such as off a CDROM)
! 114: may fail under certain circumstances (e.g. when creating a symlink on sparc
! 115: whose target name is exactly 33 characters). As a workaround you have to
! 116: either provide the source tree read/write, or install a newer version of
! 117: /usr/bin/readlink.
! 118: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/readlink.c>
! 119: A replacement source file exists</a>.
! 120: <p>
! 121: <a name=mountd></a>
! 122: <li><font color=#009000><strong>SECURITY FIX</strong></font><br>
! 123: If a line in /etc/exports which contains hostnames results in an empty
! 124: list because none of the supplied hostnames is known, mountd(8) will
! 125: accidentally export the filesystem to the world.
! 126: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/mountd.patch>
! 127: A patch is available which corrects this behaviour</a>.
! 128: <p>
! 129: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
! 130: Setting the MSG_EOR flag on a tcp packet in the send(2) family of
! 131: system calls could cause a kernel panic.
! 132: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/common/send.patch>
! 133: A patch</a> to return EINVAL in this case is available.

! 139: <a name=f00f></a>
! 140: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
! 141: The Intel P5 F00F bug was discovered after the CDR's had already been
! 142: sent to the manufacturer. This problem permits any user who has an account
! 143: to lock your machine up using a 4-line program. The problem only affects
! 144: Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable,
! 145: nor are processors by other manufacturers).
! 146: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/f00f.patch>
! 147: A kernel source-code patch is available</a>.
! 148: <p>
! 149: <li><font color=#009000><strong>FUNCTIONALITY FIX</strong></font><br>
! 150: Some Linux binaries will execute in SVR4 emulation mode, which is
! 151: definately a problem for people who need Linux emulation to work correctly.
! 152: To solve this mis-identification problem,
! 153: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/compat_linux.patch>
! 154: a patch file is provided</a>.
! 155: <p>
! 156: <li><font color=#009000><strong>RELIABILITY FIX</strong></font><br>
! 157: APM can crash on machines without it.
! 158: <a href=ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.2/i386/apm.patch>
! 159: A kernel source-code patch is available</a>.
! 160: <p>
! 161: <li><font color=#009000><strong>INSTALLATION PROCESS FLAW</strong></font><br>
! 162: A few people are running into this problem, particularily if they had some
! 163: other *BSD operating system on their machine before trying OpenBSD: if after
! 164: installation onto an IDE-based machine, the kernel fails to mount the root
! 165: partition because it thinks that it should be opening sd0 (0x400), this means
! 166: you have incorrectly setup your disklabel for the IDE drive -- the disklabel
! 167: is indicating that the drive is SCSI.
! 168: To repair this, use the floppy to run "disklabel -E wd0", then using the
! 169: "edit" command ensure the type field is set to "ST506".

! 175: <li><font color=#009000><strong>NEW SOFTWARE</strong></font><br>
! 176: Unfortunately, X11 binaries for the mac68k did not manage to make it onto the
! 177: CDROM. However, X11 for the mac68k is immediately available from
! 178: <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz">

! 184: As shipped on the CDROM, both the

! 191: Both <strong>should</strong> extract a kernel named <tt>/bsd</tt>, but they extract
! 192: the kernel into <tt>/usr/src/sys/arch/mac68k/compile</tt> instead.
! 193: <p>
! 194: This has been fixed on the ftp release of <a href=22.html>OpenBSD 2.2</a>, and
! 195: fresh kernels are available from <a href="ftp://ftp.openbsd.org/pub/OpenBSD/2.2/mac68k">
! 196: ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/</a>. If at all possible,
! 197: installing these kernels is recommended.
! 198: <p>
! 199: A number of possible workarounds exist if you don't have easy access to ftp
! 200: the updated kernels. The simplest of these is to use a
! 201: MacOS program to uncompress and untar the kernel aad use the Installer's
! 202: mini-shell to "cpin" the kernel. Alternately, you could install the kernel
! 203: with the Installer and use the mini-shell to move the binary from <tt>/usr/src/...</tt> to <tt>/bsd</tt>.
