Unquoted Windows search path vulnerability in the QEMU Guest Agent service for Red Hat Enterprise Linux Desktop 6, HPC Node 6, Server 6, Workstation 6, Desktop Supplementary 6, Server Supplementary 6, Supplementary AUS 6.4, Supplementary EUS 6.4.z, and Workstation Supplementary 6, when installing on Windows, allows local users to gain privileges via a crafted program in an unspecified folder.

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-587:04 advisory.

    KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.
    Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual     machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
    Security issues fixed with this release:
     CVE-2013-2231     No information available at the time of writing, please refer to the CVE link below.

Updated qemu-kvm packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running virtual machines using KVM.

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.

All users of qemu-kvm should upgrade to these updated packages, which contain backported patches to correct this issue. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

An updated virtio-win package that fixes one security issue is now available for Red Hat Enterprise Linux 6 Supplementary.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.
