Denial of service vulnerability in SPICE
A remote user able to initiate a SPICE connection to an application acting as a SPICE server could use this flaw to crash the application.
SPICE is an open source, adaptive remote rendering protocol used by Red Hat Enterprise Virtualization for Desktops to connect users to their virtual desktops. Unlike first-generation remote rendering protocols, such as Remote Desktop Protocol (RDP) and Independent Computing Architecture (ICA), SPICE features a multitiered architecture designed to support today's multimedia desktop experience.
