RHEL 6 : spice-xpi (RHSA-2011:0426)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated spice-xpi package that fixes two security issues is now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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)

It was found that the SPICE Firefox plug-in used a predictable name
for one of its log files. A local attacker could use this flaw to
conduct a symbolic link attack, allowing them to overwrite arbitrary
files accessible to the user running Firefox. (CVE-2011-0012)

Users of spice-xpi should upgrade to this updated package, which
contains backported patches to correct these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
