The remote host is affected by the vulnerability described in GLSA-201406-29 (spice-gtk: Privilege escalation)

    spice-gtk does not properly sanitize the DBUS_SYSTEM_BUS_ADDRESS       environment variable.
  Impact :

    A local attacker may be able to gain escalated privileges.
  Workaround :

    There is no known workaround at this time.

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.
