## Description

Multiple heap-based buffer overflows in the cirrus\_invalidate\_region
function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and
possibly other products, might allow local users to execute arbitrary code
via unspecified vectors related to "attempting to mark non-existent regions
as dirty," aka the "bitblt" heap overflow.
