Red Hat: 2010:0632-03: qspice-client: Moderate Advisory
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 qspice-client package provides the client side of the SPICE protocol.
A race condition was found in the way the SPICE Mozilla Firefox plug-in and
the SPICE client communicated. A local attacker could use this flaw to
trick the plug-in and the SPICE client into communicating over an
attacker-controlled socket, possibly gaining access to authentication
details, or resulting in a man-in-the-middle attack on the SPICE
connection. (CVE-2010-2792)
Users of qspice-client should upgrade to this updated package, which
contains a backported patch to correct this issue.
