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)
All users of spice-gtk are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
To resolve dependencies gtk2, libcacard, libusb1, and spice-protocol have been added to the necessary repositories.
