Background - -The primary interface used for network driver configuration is ioctl(2). -Several ioctl(2) commands are reserved for driver-specific purposes. For -instance, a driver may use one of these ioctls to implement an interface for -updating device firmware. - -II. Problem Description - -The driver-specific ioctl(2) command handlers in oce(4) failed to check -whether the caller has sufficient privileges to perform the corresponding -operation. - -III. Impact - -The oce(4) handler permits unprivileged users to send passthrough commands to -device firmware. - -IV. Workaround - -No workaround is available. Systems that do not contain devices driven by -oce(4) are unaffected. - -V. Solution - -Upgrade your vulnerable system to a supported FreeBSD stable or -release / security branch (releng) dated after the correction date, -and reboot. - -Perform one of the following: - -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 -# shutdown -r +10min "Rebooting for a security update" - -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-20:05/if_oce_ioctl.patch -# fetch https://security.FreeBSD.org/patches/SA-20:05/if_oce_ioctl.patch.asc -# gpg --verify if_oce_ioctl.patch.asc - -b) Apply the patch.
