How to fix?

Upgrade RHEL:6 qemu-kvm to version 2:0.12.1.2-2.209.el6 or higher.
This issue was patched in RHSA-2011:1531.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm package and not the qemu-kvm package as distributed by RHEL. See How to fix? for RHEL: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.
