RHEL 6 : spice-gtk (RHSA-2012:1284)

high Nessus Plugin ID 62170

Synopsis

The remote Red Hat host is missing a security update for spice-gtk.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:1284 advisory.

The spice-gtk packages provide a GIMP Toolkit (GTK+) widget for SPICE (Simple Protocol for Independent Computing Environments) clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol.

It was discovered that the spice-gtk setuid helper application, spice-client-glib-usb-acl-helper, did not clear the environment variables read by the libraries it uses. A local attacker could possibly use this flaw to escalate their privileges by setting specific environment variables before running the helper application. (CVE-2012-4425)

Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for reporting this issue.

All users of spice-gtk are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL spice-gtk package based on the guidance in RHSA-2012:1284.
