Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 10.04 LTS

Summary:

QEMU could be made to crash or run programs if it received specially crafted network traffic.

Software Description: - qemu-kvm: Machine emulator and virtualizer

Details:

It was discovered that QEMU incorrectly handled certain e1000 packet sizes. In certain environments, an attacker may use this flaw in combination with large packets to cause a denial of service or execute arbitrary code in the guest.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10:
qemu-kvm 1.2.0+noroms-0ubuntu2.12.10.2

Ubuntu 12.04 LTS:
qemu-kvm 1.0+noroms-0ubuntu14.7

Ubuntu 11.10:
qemu-kvm 0.14.1+noroms-0ubuntu6.6

Ubuntu 10.04 LTS:
qemu-kvm 0.12.3+noroms-0ubuntu9.21

After a standard system update you need to restart your virtual machines to make all the necessary changes.
