This issue was patched in ELSA-2011-1531.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-tools package and not the qemu-kvm-tools package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier does not properly drop group privileges when the -runas option is used, which allows local guest users to access restricted files on the host.
