This is the OpenBSD 2.2 release errata & patch list:

• All architectures

  • SECURITY FIX
    An exploitable buffer mismanagement exists in a subroutine used by lprm and lpd. The problem is exploitable by users on a particular machine if there is an entry in /etc/printcap which points at a remote printer. A patch is available which corrects this behaviour.

  • SECURITY FIX
    A DNS-based vulnerability exists when uucpd is used. By default uucpd is not enabled in the OpenBSD releases, but some sites may have enabled it. A patch is available which corrects this behaviour.

  • SECURITY FIX
    A vulnerability exists when (and only when) /etc/named.conf has the fake-iquery option enabled. A patch is available which corrects this behaviour.

  • SECURITY FIX
    A vulnerability exists in ping(8); if the -R option is used to record routes, an attacker can spoof a reply packet that will overflow inside ping. Preliminary investigation makes it look the worst attack possible is to make ping crash, but one never knows... A patch is available which corrects this behaviour.

  • SECURITY FIX
    If the sysctl variable net.inet.ip.forwarding is enabled (value 1), but the variable net.inet.ip.sourceroute is disabled (value 0), the kernel will block source routed packets from going through, but will still accept source routing packets destined for itself. Our fix changes the net.inet.ip.sourceroute variable semantics to mean that all source routed packets should be blocked completely. A kernel patch is provided.

  • SECURITY FIX
    A combination localhost+remote host security problem exists if a local user running a setuid binary causes a non-existant root .rhosts file to be created via a symbolic link with a specific kind of corefile, and then subsequently uses rsh/rlogin to enter the machine from remote. A similar exploit might also be possible using sshd which lacks any code for checking for deviations from the expected format in the .rhosts or .shosts files, but we have not confirmed this yet. The following two fixes are recommended:
    • (1) A kernel patch which adds a new sysctl option which permits the administrator to decide whether setuid corefiles should be written or not.

    • (2) Replaces the libc ruserok() function with a more paranoid version which detects bogus looking .rhosts files better.

    If the first patch is used to stop setuid coredumps, then the second patch is not as important. This problem is fixed much better in OpenBSD-current, where the kernel's symbolic link handling has been improved such that coredumping will not create a file on the other side of a symbolic link. Such a patch is not possible for the 4.4lite1 VFS layer in the OpenBSD 2.2 kernel.

    The problem with the ruserok() function appears to also exist in ssh 1.2.21 and previous (the ssh people have been alerted).

  • SECURITY FIX
    A bug in the vm system permits a file descriptor opened read-only on a device, to later on be mmap(2)'d read-write, and then modified. This does not result in a security hole by itself, but it does violate the safety semantics which securelevels are supposed to provide. If a user manages to gain kmem group permissions, using this problem they can then gain root trivially and/or turn securelevels off. A kernel patch is available which corrects this behaviour (this is revision 3 of this patch).

  • BUILD PROCESS FIX
    Building an object tree from a read-only source tree (such as off a CDROM) may fail under certain circumstances (e.g. when creating a symlink on sparc whose target name is exactly 33 characters). As a workaround you have to either provide the source tree read/write, or install a newer version of /usr/bin/readlink. A replacement source file exists.

  • SECURITY FIX
    If a line in /etc/exports which contains hostnames results in an empty list because none of the supplied hostnames is known, mountd(8) will accidentally export the filesystem to the world. A patch is available which corrects this behaviour.

  • RELIABILITY FIX
    Setting the MSG_EOR flag on a tcp packet in the send(2) family of system calls could cause a kernel panic. A patch to return EINVAL in this case is available.

• i386

  • RELIABILITY FIX
    The Intel P5 F00F bug was discovered after the CDR's had already been sent to the manufacturer. This problem permits any user who has an account to lock your machine up using a 4-line program. The problem only affects Intel P5 processors (the i386, i486, P-Pro, and P-II are not vulnerable, nor are processors by other manufacturers). A kernel source-code patch is available.

  • FUNCTIONALITY FIX
    Some Linux binaries will execute in SVR4 emulation mode, which is definately a problem for people who need Linux emulation to work correctly. To solve this mis-identification problem, a patch file is provided.

  • RELIABILITY FIX
    APM can crash on machines without it. A kernel source-code patch is available.

  • INSTALLATION PROCESS FLAW
    A few people are running into this problem, particularily if they had some other *BSD operating system on their machine before trying OpenBSD: if after installation onto an IDE-based machine, the kernel fails to mount the root partition because it thinks that it should be opening sd0 (0x400), this means you have incorrectly setup your disklabel for the IDE drive -- the disklabel is indicating that the drive is SCSI. To repair this, use the floppy to run "disklabel -E wd0", then using the "edit" command ensure the type field is set to "ST506".

• mac68k

  • NEW SOFTWARE
    Unfortunately, X11 binaries for the mac68k did not manage to make it onto the CDROM. However, X11 for the mac68k is immediately available from ftp://ftp.OpenBSD.org/pub/OpenBSD/2.2/mac68k/X11/X11R6.tar.gz. Please be sure to read the README file also in that directory for instructions on installing and setting up X.

  • INSTALLATION PROCESS FLAW
    As shipped on the CDROM, both the generic kernel and the genericsbc kernel extract themselves into the wrong place in the filesystem. Both should extract a kernel named /bsd, but they extract the kernel into /usr/src/sys/arch/mac68k/compile instead.

    This has been fixed on the ftp release of OpenBSD 2.2, and fresh kernels are available from ftp://ftp.OpenBSD.ORG/pub/OpenBSD/2.2/mac68k/. If at all possible, installing these kernels is recommended.

    A number of possible workarounds exist if you don't have easy access to ftp the updated kernels. The simplest of these is to use a MacOS program to uncompress and untar the kernel aad use the Installer's mini-shell to "cpin" the kernel. Alternately, you could install the kernel with the Installer and use the mini-shell to move the binary from /usr/src/... to /bsd.

• sparc

  • RELIABILITY FIX
    Older 4/xxx systems (particularily the 4/300's) cannot boot with the 2.2 kernel due to bugs in the scsi device driver. A kernel source patch is available. Replacement kernels are available for: bsd, bsd.scsi3, and a replacement for bsd.rd is coming soon.

  • RELIABILITY FIX
    SPARCstation 4 and 5 (Microsparc 2) users may see kernel panics when using a custom kernel configured for option sun4m only. A workaround (kernel source patch) is available. Apply the patch and then re-build your kernel.

• amiga

  • FUNCTIONALITY FIX
    Missing Xamiga manual pages. Get this package and execute, as root:
    # pkg_add Xamiga-manual.tgz
    The MD5 checksum of this package is:
    MD5 (Xamiga-manual.tgz) = 2362a7857264b9d17f65cca258b42031

  • FUNCTIONALITY FIX
    The Ariadne ethernet support was broken, there will be both binary and source level fixes available shortly. If you are in a hurry mail Niklas for a test kernel.

• pmax

  • FUNCTIONALITY FIX
    There is a Year-1998 problem in the time-setting code (which causes the date and time to be set incorrectly after a reboot in 1998). A source code patch file is available plus replacement installation kernels for the 2.2 release at bsd.NFS, bsd, bsd.rz0.

  • FUNCTIONALITY FIX
    X11 support for the 3min and 3maxplus machines was broken due to a kernel bug. A source code patch is available.

  • SECURITY FIX
    A security problem in the shared library linker ld.so requires that you replace it with a new binary. The following binary will work on both pmax and arc machines. The replacement binary is here.

• arc

  • SECURITY FIX
    A security problem in the shared library linker ld.so requires that you replace it with a new binary. The following binary will work on both pmax and arc machines. The replacement binary is here.

• alpha

  • MISSING FUNCTIONALITY
    Network Address Translation and other parts of IP Filtering to not work on the alpha. This will be fixed in the 2.3 release, and perhaps earlier in a snapshot. There is no patch for 2.2.
