-From 6eff47e72cb2f23d168be58bab8bdd60df49afd0 Mon Sep 17 00:00:00 2001

-Subject: [spice-server] memslot: Fix off-by-one error in group/slot boundary
- check
-
-RedMemSlotInfo keeps an array of groups, and each group contains an
-array of slots. Unfortunately, these checks are off by 1, they check
-that the index is greater or equal to the number of elements in the
-array, while these arrays are 0 based. The check should only check for
-strictly greater than the number of elements.
-
-For the group array, this is not a big issue, as these memslot groups
-are created by spice-server users (eg QEMU), and the group ids used to
-index that array are also generated by the spice-server user, so it
-should not be possible for the guest to set them to arbitrary values.
-
-The slot id is more problematic, as it's calculated from a QXLPHYSICAL
-address, and such addresses are usually set by the guest QXL driver, so
-the guest can set these to arbitrary values, including malicious values,
-which are probably easy to build from the guest PCI configuration.
-
-This patch fixes the arrays bound check, and adds a test case for this.
-
