Detail

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

- Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS

Summary:

QEMU could be made to overwrite files as the administrator, or expose sensitive information.

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

Details:

It was discovered that QEMU incorrectly handled temporary files when creating a snapshot. A local attacker could use this flaw to possibly overwrite files with root privilege, or obtain sensitive information from the guest.

Update instructions:

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

Ubuntu 12.04 LTS:
qemu-kvm 1.0+noroms-0ubuntu14.1

Ubuntu 11.10:
qemu-kvm 0.14.1+noroms-0ubuntu6.4

Ubuntu 11.04:
qemu-kvm 0.14.0+noroms-0ubuntu4.6

Ubuntu 10.04 LTS:
