Subject: [Qemu-devel] [PATCH v3 0/5] vmware-vga: fix CVE-2014-3689
Date: Tue, 28 Oct 2014 10:50:37 +0100 [thread overview]
Message-ID: <1414489842-27535-1-git-send-email-kraxel@redhat.com> (raw)
Hi,
vmware-vga emulation lacks sanity checks in the hardware acceleration
(blit + fill) functions. This patch series plugs the holes.
v3 changes:
* throw badcmd errors in case the rectangles fail the sanity checks.
v2 changes:
* small whitespace fixup.
* do fullscreen update on invalid update requests.
cheers,
Gerd
