Qemu: ui: vnc: avoid floating point exception
Qemu, when built with VNC display driver support, allows remote attackers to cause a denial of service (arithmetic exception and application crash) via crafted SetPixelFormat messages from a client.
An arithmetic-exception flaw was found in the QEMU emulator built with VNC display-driver support. The VNC server incorrectly handled 'SetPixelFormat' messages sent from clients. A privileged remote client could use this flaw to crash the guest resulting in denial of service.
Statement: This issue does not affect the versions of the kvm and xen packages as shipped with Red Hat Enterprise Linux 5.

CVE-2015-8504 Qemu: ui: vnc: avoid floating point exception
Qemu emulator built with the VNC display driver support is vulnerable to an
arithmetic exception flaw. It occurs on the VNC server side while processing
the 'SetPixelFormat' messages from a client.
A privileged remote client could use this flaw to crash the guest resulting in
DoS.
