CVE-2014-7840 [HIGH] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Michael S. Tsirkin discovered that QEMU incorrectly handled certain
parameters during ram load while performing a migration. An attacker able
to manipulate savevm data could use this issue to possibly execute
arbitrary code on the host. This issue only affected Ubuntu 12.04 LTS,
Ubuntu 14.04 LTS, and Ubuntu 14.10. (CVE-2014-7840)
Paolo Bonzini discovered that QEMU incorrectly handled memory in the Cirrus
VGA device. A malicious guest could possibly use this issue to write into
memory of the host, leading to privilege escalation. (CVE-2014-8106)
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.

CVE-2007-1320 xen/qemu Cirrus LGD-54XX "bitblt" Heap Overflow
The cirrus_invalidate_region() routine used during video-to-video copy
operations in the cirrus vga extension code omits bounds checking in
multiple locations, allowing you to overwrite adjacent buffers by
attempting to mark non-existent regions as dirty. Successful
exploitation would result in a complete compromise of the qemu
process. Additionally multiple bitblt operations omit bounds checking,
where the srcpitch or dstpitch coefficients cause the operation to
exceed the bounds of the vram buffer.
