========================================================================== Ubuntu Security Notice USN-1339-1 January 23, 2012
qemu-kvm vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
A remote attacker could cause QEMU to crash.
Software Description: - qemu-kvm: Machine emulator and virtualizer
Details:
Nicolae Mogoreanu discovered that QEMU did not properly verify legacy mode packets in the e1000 network driver. A remote attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
When using QEMU with libvirt or virtualization management software based on libvirt such as Eucalyptus and OpenStack, QEMU guests are individually isolated by an AppArmor profile by default in Ubuntu.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: qemu-kvm 0.14.1+noroms-0ubuntu6.2
Ubuntu 11.04: qemu-kvm 0.14.0+noroms-0ubuntu4.5
Ubuntu 10.10: qemu-kvm 0.12.5+noroms-0ubuntu7.11 qemu-kvm-extras 0.12.5+noroms-0ubuntu7.11 qemu-kvm-extras-static 0.12.5+noroms-0ubuntu7.11
Ubuntu 10.04 LTS: qemu-kvm 0.12.3+noroms-0ubuntu9.17 qemu-kvm-extras 0.12.3+noroms-0ubuntu9.17 qemu-kvm-extras-static 0.12.3+noroms-0ubuntu9.17
After a standard system update you need to restart running virtual machines which use the e1000 network driver to make all the necessary changes.
