An unquoted search path flaw was found in the way the Red Hat Enterprise Virtualization agent 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-2013-2151)

An unquoted search path flaw was found in the way the SPICE 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-2013-2152)

This update also fixes the following bugs :

* Previously, when trying to uninstall rhev-guest-tools in Windows Server 2003 (both 32-bit and 64-bit), an error event was created in the event viewer saying 'The BalloonService service hung on starting', even though the package was uninstalled correctly. Now, the balloon service executable is no longer registered meaning the service is no longer running by default and rhev-guest-tools can be uninstalled without any error messages. (BZ#860225, BZ#880278)

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

Solution

Update the affected rhev-guest-tools-iso package.
