Red Hat: 2013:1101-01: virtio-win: Important Advisory
Summary
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.
