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 rhev-guest-tools-iso package contains tools and drivers. These tools and drivers are required by supported Windows guest operating systems when installed as guests on Red Hat Enterprise Virtualization.

An unquoted search path flaw was found in the way the Red Hat Enterprise Virtualization Application Provisioning Tool (RHEV-APT) service was installed 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-2013-2176)

This issue was discovered by Jiri Belka of Red Hat.

This update also fixes the following bugs :

* In rare cases the format of the temporary directory location, as returned by the Windows operating system, did not match the format expected by the RHEV-Tools installer. Consequently, the install or upgrade failed with a warning 'Upgrade of RHEV-Tools on the Guest should be performed only when running on RHEL 6 type Host (RHEV-H or RHEL). Upgrade aborted.' This update adds code to handle these exceptional cases, so RHEV-Tools can be successfully installed or updated on Windows virtual machines. (BZ#979108)

* This release includes an updated Virtio-Serial driver and SPICE Agent. (BZ#986904)

This rhev-guest-tools-iso package also contains a spice-vdagent-win bug fix update (RHBA-2013:1107):

All Red Hat Enterprise Virtualization users are advised to upgrade to this updated rhev-guest-tools-iso package, which resolves these issues.
