========================================================================== Ubuntu Security Notice USN-1522-1 August 02, 2012
qemu-kvm vulnerability ==========================================================================
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: qemu-kvm 0.12.3+noroms-0ubuntu9.19
In general, a standard system update will make all the necessary changes.
