qemu-kvm vulnerability

Packages

  • 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
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

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