Description

The virtio-win package provides paravirtualized network drivers for most Microsoft Windows operating systems. Paravirtualized drivers are virtualization-aware drivers used by fully virtualized guests running on Red Hat Enterprise Linux.

An unquoted search path flaw was found in the way the QEMU Guest Agent service installation was performed on Windows. Depending on the permissions of the directories in the unquoted search path, a local, unprivileged user could use this flaw to have a binary of their choosing executed with SYSTEM privileges. (CVE-2013-2231)

This issue was discovered by Lev Veyde of Red Hat.

Users of virtio-win are advised to upgrade to this updated package, which corrects this issue.
