The x86 emulator implementation was missing a check for the Current Privilege Level (CPL) and I/O Privilege Level (IOPL). A user in a guest could leverage these flaws to cause a denial of service (guest crash) or possibly escalate their privileges within that guest.
(CVE-2010-0298, CVE-2010-0306)

A flaw was found in the Programmable Interval Timer (PIT) emulation.
Access to the internal data structure pit_state, which represents the data state of the emulated PIT, was not properly validated in the pit_ioport_read() function. A privileged guest user could use this flaw to crash the host. (CVE-2010-0309)

A flaw was found in the USB passthrough handling code. A specially crafted USB packet sent from inside a guest could be used to trigger a buffer overflow in the usb_host_handle_control() function, which runs under the QEMU-KVM context on the host. A user in a guest could leverage this flaw to cause a denial of service (guest hang or crash) or possibly escalate their privileges within the host. (CVE-2010-0297)

This update also fixes the following bugs :

  - pvclock MSR values were not preserved during remote     migration, causing time drift for guests. (BZ#537028)

  - SMBIOS table 4 data is now generated for Windows guests.
    (BZ#545874)

  - if the qemu-kvm '-net user' option was used, unattended     Windows XP installations did not receive an IP address     after reboot. (BZ#546562)

  - when being restored from migration, a race condition     caused Windows Server 2008 R2 guests to hang during     shutdown. (BZ#546563)

  - the kernel symbol checking on the kvm-kmod build process     has a safety check for ABI changes. (BZ#547293)

  - on hosts without high-res timers, Windows Server 2003     guests experienced significant time drift. (BZ#547625)

  - in some situations, installing Windows Server 2008 R2     from an ISO image resulted in a blue screen     'BAD_POOL_HEADER' stop error. (BZ#548368)

  - a bug in the grow_refcount_table() error handling caused     infinite recursion in some cases. This caused the     qemu-kvm process to hang and eventually crash.
    (BZ#552159)

  - for Windows Server 2003 R2, Service Pack 2, 32-bit     guests, an 'unhandled vm exit' error could occur during     reboot on some systems. (BZ#552518)

  - for Windows guests, QEMU could attempt to stop a stopped     audio device, resulting in a 'snd_playback_stop: ASSERT     playback_channel->base.active failed' error. (BZ#552519)

  - the Hypercall driver did not reset the device on     power-down. (BZ#552528)

  - mechanisms have been added to make older savevm versions     to be emitted in some cases. (BZ#552529)

  - an error in the Makefile prevented users from using the     source RPM to install KVM. (BZ#552530)

  - guests became unresponsive and could use up to 100% CPU     when running certain benchmark tests with more than 7     guests running simultaneously. (BZ#553249)

  - QEMU could terminate randomly with virtio-net and SMP     enabled. (BZ#561022)

NOTE - The following procedure must be performed before this update will take effect :

1) Stop all KVM guest virtual machines.

2) Either reboot the hypervisor machine or, as the root user, remove (using 'modprobe -r [module]') and reload (using 'modprobe [module]') all of the following modules which are currently running (determined using 'lsmod'): kvm, ksm, kvm-intel or kvm-amd.

3) Restart the KVM guest virtual machines.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-3939     Joseph Malicki reported that the dbg_lvl sysfs attribute     for the megaraid_sas device driver had world-writable     permissions, permitting local users to modify logging     settings.

  - CVE-2009-4027     Lennert Buytenhek reported a race in the mac80211     subsystem that may allow remote users to cause a denial     of service (system crash) on a system connected to the     same wireless network.

All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

Several local vulnerabilities have been discovered in kvm, a full virtualization system. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-0298 CVE-2010-0306     Gleb Natapov discovered issues in the KVM subsystem     where missing permission checks (CPL/IOPL) permit a user     in a guest system to denial of service a guest (system     crash) or gain escalated privileges with the guest.

  - CVE-2010-0419     Paolo Bonzini found a bug in KVM that can be used to     bypass proper permission checking while loading segment     selectors. This potentially allows privileged guest     users to execute privileged instructions on the host     system.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0088 advisory.

  - kvm-userspace-rhel5: usb-linux.c: fix buffer overflow (CVE-2010-0297)

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2010-0298 advisory.

  - The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL)     in determining the memory access available to CPL3 code, which allows guest OS users to cause a denial of     service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2)     MMIO region, a related issue to CVE-2010-0306.
