Description Petr Matousek 2014-10-15 13:02:21 UTC

A flaw was found in the way guest provided parameter validation was performed
in vmware-vga driver in rectangle handling functionality.

A privileged guest user could use this flaw to write into qemu address space
on the host, pontentially escalating their privileges to that of qemu host
process.

Proposed upstream fix:
