Actual commit IDs from the master branch, with some comments
(with just one useful for 1.3 comment, about e1000 security fix):

This is applicable to old qemu-kvm (pre-1.3-merge), so it is qemu-kvm 1.1
and qemu-kvm 1.2.  I missed it for 1.1 because it is qemu-kvm-specific.
Queued for debian qemu-kvm package.

Guys, this is just one half of the CVE-2012-6075 fix.
Please don't repeat the same mistake again and again.
Second patch by Michael is neede to fix this too.

Note that recent Xen advisory (Xen Security Advisory 41)
has the same issu, they fixed just the half of it.

Both are applied to stable-1.1.

post-1.2 material, needs 938b8a36b65e44c44ca29245437f8d7ac0f826e8 and probably
a bunch of other stuff.
