Bug 567828 – <app-emulation/qemu-2.4.1-r2: ui: vnc: avoid floating point exception (CVE-2015-8504)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Agostino Sarubbo 2015-12-09 10:54:18 UTC]

From ${URL} :

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 'SetPixleFormat' messages from a client.

A privileged remote client could use this flaw to crash the guest resulting in 
DoS.
