[PATCH] Security: Mitigate possible privilege escalation via SG_IO ioctl (CVE-2011-4127, RHBZ#757071)
by Richard W.M. Jones 22 Dec '11

22 Dec '11

From: "Richard W.M. Jones" <rjones(a)redhat.com> CVE-2011-4127 is a serious qemu & kernel privilege escalation bug found by Paolo Bonzini. http://seclists.org/oss-sec/2011/q4/536 An untrusted guest kernel is able to issue special SG_IO ioctls on virtio devices which qemu passes through to the host kernel without filtering or sanitizing. These ioctls allow raw sectors from the underlying host device to be read and written. Significantly, neither qemu nor the host kernel checks that the range of sectors is within the partition / LV assigned to the guest. For example, if the guest is assigned host partition /dev/sda3, it would be able to read or write any part of /dev/sda including other partitions and the boot sector. Exploits through LVs passed to the guest are also possible, with some limitations. File-backed virtual block devices are not vulnerable. Non-virtio block devices are not vulnerable. This patch mitigates the problem by disabling the SG_IO ioctl passthrough in qemu. Thus if libguestfs is examining an untrusted guest and the libguestfs appliance/daemon is compromised (eg. by executing guest commands, or through some other compromise), then the compromised appliance will not be able to issue the above SG_IO ioctls and exploit the host. Note that this is just mitigation for libguestfs. Users will still want to fully update their host kernel, qemu/KVM and libvirt, in order to prevent other (non-libguestfs) routes to compromise. The following versions of libguestfs (will/have) this patch applied. libguestfs >= 1.15.13 libguestfs >= 1.14.8 libguestfs >= 1.12.11 libguestfs >= 1.10.12 libguestfs >= 1.8.16 Earlier versions may be vulnerable unless a downstream packager has applied this patch.

FYI: Changes to test directory names
by Richard W.M. Jones 22 Dec '11

22 Dec '11

I'm going to rename some test directories to make the names more logical: * caution -> tests/qemu This directory contains tests of qemu (safety and liveness). 'make check' will be changed so that this directory is tested first. At present, 'make check' happens to build images/ first which makes it harder to track down qemu breakage. * capitests -> tests/c-api Tests of the C API. Arguably these tests could be moved into src/ but that directory has lots of files in it already. * regressions -> tests/regressions + tests/protocol + tests/luks + tests/... Split this directory into true regression tests, and tests of other things. guestfish-specific tests will be placed in the fish/ directory instead of being in a separate directory. This makes it consistent with other C tools such as virt-df, virt-edit where tests are located in the same directory as the tool. * extratests -> tests/extra Complex tests that require valgrind, local guests, etc. Just as now, these are not part of 'make check'. * images -> tests/data + tests/guests Split into test data, and the (phony) guest images. tests/data (as now) doesn't contain any TESTS (just data required by other tests). It is built early during the 'make' phase. tests/guests: Because other tests rely on these guests, we will build it early (after tests/qemu, before tests/c-api). The guests are check_DATA, meaning they get created during 'make check'. * test-tool (no change) These changes will first be done on master (development) so we can shake out bugs. I plan to backport them to the 1.14 branch at a later date.

Proposed changes for OpenStack
by Richard W.M. Jones 15 Dec '11

15 Dec '11

[These two patches are for discussion only] Allow FUSE support to be used directly through the API. This is the second commit. In order to make this usable from guestfish, we have to also bind the events API in guestfish. This is the first commit. Rich.

Help loading a corrupt vdi file
by op 157 15 Dec '11

15 Dec '11

Hello everyone, I have a corrupt .vdi file from a virtualbox installation (XP host, Mint 11 guest) which I recently broke. I wanted to allocate more space to it, so I ran this command:VBoxManage.exe modifyhd /path/to/YOUR_HARD_DISK.vdi --resize 17179869184 It only took a second to actually complete, so I think a header somewhere is broken. I need to get access to some files I had on there using libguestfs on a Mint Virtualbox I have, and I'm trying to mount the bad vdi file to get access to everything, but that isn't working. I have this output from libguestfs-test-tool, can anyone help?:Thanks! libguestfs: new guestfs handle 0x10242d0libguestfs: [00000ms] febootstrap-supermin-helper --verbose -f checksum '/usr/lib/guestfs/supermin.d' x86_64supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null)supermin helper [00001ms] inputs[0] = /usr/lib/guestfs/supermin.dchecking modpath /lib/modules/2.6.38-8-generic is a directorypicked vmlinuz-2.6.38-8-generic because modpath /lib/modules/2.6.38-8-generic existssupermin helper [00001ms] finished creating kernelsupermin helper [00002ms] visiting /usr/lib/guestfs/supermin.dsupermin helper [00002ms] visiting /usr/lib/guestfs/supermin.d/base.imgsupermin helper [00007ms] visiting /usr/lib/guestfs/supermin.d/daemon.imgsupermin helper [00007ms] visiting /usr/lib/guestfs/supermin.d/hostfilessupermin helper [00142ms] visiting /usr/lib/guestfs/supermin.d/init.imgsupermin helper [00142ms] adding kernel modulessupermin helper [00341ms] finished creating appliancelibguestfs: [00373ms] begin testing qemu featureslibguestfs: [00551ms] finished testing qemu featureslibguestfs: accept_from_daemon: 0x10242d0 g->state = 1libguestfs: is_openable: /dev/kvm: No such file or directory[00563ms] /usr/bin/kvm \ -drive file=/tmp/libguestfs-test-tool-sda-rZ97hB,cache=off,format=raw,if=virtio \ -nodefconfig \ -nodefaults \ -nographic \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -chardev socket,path=/tmp/libguestfsEjpY0b/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-0/kernel.2125 \ -initrd /var/tmp/.guestfs-0/initrd.2125 \ -append 'panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=xterm ' \ -drive file=/var/tmp/.guestfs-0/root.2125,snapshot=on,if=virtio,cache=unsafeopen /dev/kvm: No such file or directoryCould not initialize KVM, will disable KVM support[ 0.000000] Initializing cgroup subsys cpuset[ 0.000000] Initializing cgroup subsys cpu[ 0.000000] Linux version 2.6.38-8-generic (buildd@allspice) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu3) ) #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 (Ubuntu 2.6.38-8.42-generic 2.6.38.2)[ 0.000000] Command line: panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=xterm [ 0.000000] BIOS-provided physical RAM map:[ 0.000000] BIOS-e820: 0000000000000000 - 000000000009bc00 (usable)[ 0.000000] BIOS-e820: 000000000009bc00 - 00000000000a0000 (reserved)[ 0.000000] BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved)[ 0.000000] BIOS-e820: 0000000000100000 - 000000001f3fd000 (usable)[ 0.000000] BIOS-e820: 000000001f3fd000 - 000000001f400000 (reserved)[ 0.000000] BIOS-e820: 00000000fffc0000 - 0000000100000000 (reserved)[ 0.000000] NX (Execute Disable) protection: active[ 0.000000] DMI 2.4 present.[ 0.000000] No AGP bridge found[ 0.000000] last_pfn = 0x1f3fd max_arch_pfn = 0x400000000[ 0.000000] x86 PAT enabled: cpu 0, old 0x0, new 0x7010600070106[ 0.000000] found SMP MP-table at [ffff8800000fd790] fd790[ 0.000000] init_memory_mapping: 0000000000000000-000000001f3fd000[ 0.000000] RAMDISK: 1f2c8000 - 1f3f0000[ 0.000000] No NUMA configuration found[ 0.000000] Faking a node at 0000000000000000-000000001f3fd000[ 0.000000] Initmem setup node 0 0000000000000000-000000001f3fd000[ 0.000000] NODE_DATA [000000001f3f5000 - 000000001f3f9fff][ 0.000000] Zone PFN ranges:[ 0.000000] DMA 0x00000010 -> 0x00001000[ 0.000000] DMA32 0x00001000 -> 0x00100000[ 0.000000] Normal empty[ 0.000000] Movable zone start PFN for each node[ 0.000000] early_node_map[2] active PFN ranges[ 0.000000] 0: 0x00000010 -> 0x0000009b[ 0.000000] 0: 0x00000100 -> 0x0001f3fd[ 0.000000] SFI: Simple Firmware Interface v0.81 http://simplefirmware.org[ 0.000000] Intel MultiProcessor Specification v1.4[ 0.000000] MPTABLE: OEM ID: BOCHSCPU[ 0.000000] MPTABLE: Product ID: 0.1 [ 0.000000] MPTABLE: APIC at: 0xFEE00000[ 0.000000] Processor #0 (Bootup-CPU)[ 0.000000] IOAPIC[0]: apic_id 1, version 17, address 0xfec00000, GSI 0-23[ 0.000000] Processors: 1[ 0.000000] SMP: Allowing 1 CPUs, 0 hotplug CPUs[ 0.000000] PM: Registered nosave memory: 000000000009b000 - 000000000009c000[ 0.000000] PM: Registered nosave memory: 000000000009c000 - 00000000000a0000[ 0.000000] PM: Registered nosave memory: 00000000000a0000 - 00000000000f0000[ 0.000000] PM: Registered nosave memory: 00000000000f0000 - 0000000000100000[ 0.000000] Allocating PCI resources starting at 1f400000 (gap: 1f400000:e0bc0000)[ 0.000000] Booting paravirtualized kernel on bare hardware[ 0.000000] setup_percpu: NR_CPUS:256 nr_cpumask_bits:256 nr_cpu_ids:1 nr_node_ids:1[ 0.000000] PERCPU: Embedded 28 pages/cpu @ffff88001f000000 s84416 r8192 d22080 u2097152[ 0.000000] Built 1 zonelists in Node order, mobility grouping on.
