spice security update

CentOS Errata and Security Advisory CESA-2017:0253

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.

Security Fix(es):

• A vulnerability was discovered in spice in the server’s protocol handling. An authenticated attacker could send crafted messages to the spice server causing a heap overflow leading to a crash or possible code execution. (CVE-2016-9577)

• A vulnerability was discovered in spice in the server’s protocol handling. An attacker able to connect to the spice server could send crafted messages which would cause the process to crash. (CVE-2016-9578)

These issues were discovered by Frediano Ziglio (Red Hat).
