RHBA-2014:0670 - Bug Fix Advisory

Topic

Updated spice-server packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The Simple Protocol for Independent Computing Environments (SPICE) is a remote
display protocol for virtual environments. SPICE users can access a virtualized
desktop or server from the local system or any system with network access to the
server. SPICE is 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 Hypervisors.

• Under certain circumstances, the SPICE server could terminate unexpectedly

while streaming the display data in video format. As a consequence, the guest
operating system could exit. This bug has been fixed, and the SPICE server no
longer crashes. (BZ#1103827)

Users of spice-server are advised to upgrade to these updated packages, which
fix this bug.
