 following package versions:

Ubuntu 8.04 LTS:
  kvm                             1:62+dfsg-0ubuntu8.1

Ubuntu 8.10:
  kvm                             1:72+dfsg-1ubuntu6.1

After a standard system upgrade you need to restart all KVM VMs to effect
the necessary changes.

tag_insight = "Avi Kivity discovered that KVM did not correctly handle certain disk
formats.  A local attacker could attach a malicious partition that
would allow the guest VM to read files on the VM host. (CVE-2008-1945,
CVE-2008-2004)

Alfredo Ortega discovered that KVM's VNC protocol handler did not
correctly validate certain messages.  A remote attacker could send
specially crafted VNC messages that would cause KVM to consume CPU
resources, leading to a denial of service. (CVE-2008-2382)

Jan Niehusmann discovered that KVM's Cirrus VGA implementation over VNC
did not correctly handle certain bitblt operations.  A local attacker
could exploit this flaw to potentially execute arbitrary code on the VM
host or crash KVM, leading to a denial of service. (CVE-2008-4539)

It was discovered that KVM's VNC password checks did not use the correct
length.  A remote attacker could exploit this flaw to cause KVM to crash,
leading to a denial of service. (CVE-2008-5714)";
