Summary

The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol used in Red Hat Enterprise Linux for viewing virtualized guests running on the Kernel-based Virtual Machine (KVM) hypervisor, or on Red Hat Enterprise Virtualization Hypervisor.
The spice-xpi package provides a plug-in that allows the SPICE client to run from within Mozilla Firefox.
An uninitialized pointer use flaw was found in the SPICE Firefox plug-in. If a user were tricked into visiting a malicious web page with Firefox while the SPICE plug-in was enabled, it could cause Firefox to crash or, possibly, execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-1179)
Users of spice-xpi should upgrade to this updated package, which contains a backported patch to correct this issue. After installing the update, Firefox must be restarted for the changes to take effect.
