Michael Roth 1124696193 openpic: avoid buffer overrun on incoming migration
CVE-2013-4534

opp->nb_cpus is read from the wire and used to determine how many
IRQDest elements to read into opp->dst[]. If the value exceeds the
length of opp->dst[], MAX_CPU, opp->dst[] can be overrun with arbitrary
data from the wire.

Fix this by failing migration if the value read from the wire exceeds
MAX_CPU.

Michael S. Tsirkin 4e48018ae9 virtio: validate num_sg when mapping
CVE-2013-4535
CVE-2013-4536

Both virtio-block and virtio-serial read,
VirtQueueElements are read in as buffers, and passed to
virtqueue_map_sg(), where num_sg is taken from the wire and can force
writes to indicies beyond VIRTQUEUE_MAX_SIZE.

To fix, validate num_sg.

Michael Roth 7297dba271 virtio: avoid buffer overrun on incoming migration
CVE-2013-6399

vdev->queue_sel is read from the wire, and later used in the
emulation code as an index into vdev->vq[]. If the value of
vdev->queue_sel exceeds the length of vdev->vq[], currently
allocated to be VIRTIO_PCI_QUEUE_MAX elements, subsequent PIO
operations such as VIRTIO_PCI_QUEUE_PFN can be used to overrun
the buffer with arbitrary data originating from the source.

Fix this by failing migration if the value from the wire exceeds
VIRTIO_PCI_QUEUE_MAX.

Michael S. Tsirkin 9c01a91c7b vmstate: fix buffer overflow in target-arm/machine.c
CVE-2013-4531

cpreg_vmstate_indexes is a VARRAY_INT32. A negative value for
cpreg_vmstate_array_len will cause a buffer overflow.

VMSTATE_INT32_LE was supposed to protect against this
but doesn't because it doesn't validate that input is
non-negative.

Fix this macro to valide the value appropriately.

The only other user of VMSTATE_INT32_LE doesn't
ever use negative numbers so it doesn't care.

4) CVE-2013-4529
hw/pci/pcie_aer.c    pcie aer log can overrun the buffer if log_num is
                     too large

There are two issues in this file:
1. log_max from remote can be larger than on local
then buffer will overrun with data coming from state file.
2. log_num can be larger then we get data corruption
again with an overflow but not adversary controlled.

Fix both issues.

Michael S. Tsirkin d4c9095900 ahci: fix buffer overrun on invalid state load
CVE-2013-4526

Within hw/ide/ahci.c, VARRAY refers to ports which is also loaded.  So
we use the old version of ports to read the array but then allow any
value for ports.  This can cause the code to overflow.

There's no reason to migrate ports - it never changes.
So just make sure it matches.

Michael S. Tsirkin b24cfb0f1e virtio-net: out-of-bounds buffer write on invalid state load
CVE-2013-4150 QEMU 1.5.0 out-of-bounds buffer write in
virtio_net_load()@hw/net/virtio-net.c

This code is in hw/net/virtio-net.c:

    if (n->max_queues > 1) {
        if (n->max_queues != qemu_get_be16(f)) {
            error_report("virtio-net: different max_queues ");
            return -1;
        }

        n->curr_queues = qemu_get_be16(f);
        for (i = 1; i < n->curr_queues; i++) {
            n->vqs[i].tx_waiting = qemu_get_be32(f);
        }
    }

Number of vqs is max_queues, so if we get invalid input here,
for example if max_queues = 2, curr_queues = 3, we get
write beyond end of the buffer, with data that comes from
wire.

This might be used to corrupt qemu memory in hard to predict ways.
Since we have lots of function pointers around, RCE might be possible.

Michael S. Tsirkin 7872f3e77e virtio-net: fix buffer overflow on invalid state load
CVE-2013-4148 QEMU 1.0 integer conversion in
virtio_net_load()@hw/net/virtio-net.c

Deals with loading a corrupted savevm image.

>         n->mac_table.in_use = qemu_get_be32(f);

in_use is int so it can get negative when assigned 32bit unsigned value.

>         /* MAC_TABLE_ENTRIES may be different from the saved image */
>         if (n->mac_table.in_use <= MAC_TABLE_ENTRIES) {

passing this check ^^^

>             qemu_get_buffer(f, n->mac_table.macs,
>                             n->mac_table.in_use * ETH_ALEN);

with good in_use value, "n->mac_table.in_use * ETH_ALEN" can get
positive and bigger than mac_table.macs. For example 0x81000000
satisfies this condition when ETH_ALEN is 6.

Fix it by making the value unsigned.
For consistency, change first_multi as well.

Note: all call sites were audited to confirm that
making them unsigned didn't cause any issues:
it turns out we actually never do math on them,
so it's easy to validate because both values are
always <= MAC_TABLE_ENTRIES.

Peter Maydell 9ee8ab5503 hw/net/stellaris_enet: Correct handling of packet padding
The PADEN bit in the transmit control register enables padding of short
data packets out to the required minimum length. However a typo here
meant we were adjusting tx_fifo_len rather than tx_frame_len, so the
padding didn't actually happen. Fix this bug.

Peter Maydell c8723d46c1 hw/net/stellaris_enet: Restructure tx_fifo code to avoid buffer overrun
The current tx_fifo code has a corner case where the guest can overrun
the fifo buffer: if automatic CRCs are disabled we allow the guest to write
the CRC word even if there isn't actually space for it in the FIFO.
The datasheet is unclear about exactly how the hardware deals with this
situation; the most plausible answer seems to be that the CRC word is
just lost.

Implement this fix by separating the "can we stuff another word in the
FIFO" logic from the "should we transmit the packet now" check. This
also moves us closer to the real hardware, which has a number of ways
it can be configured to trigger sending the packet, some of which we
don't implement.

Michael Tokarev 50212d6346 Revert "fix return check for KVM_GET_DIRTY_LOG ioctl"
This reverts commit b533f658a9.

The original code was wrong, because effectively it ignored errors
from kernel, because kernel does not return -1 on error case but
returns -errno, and does not return -EPERM for this particular ioctl.
But in some cases kernel actually returned unsuccessful result,
namely, when the dirty bitmap in requested slot does not exist
it returns -ENOENT.  With new code this condition becomes an
error when it shouldn't be.

Revert that patch instead of fixing it properly this late in the
release process.  I disagree with this approach, but let's make
things move _somewhere_, instead of arguing endlessly whch of
the 2 proposed fixes is better.

at offset equal to in_use.

To avoid overflow of this array by guest, qemu attempts
to test the size as follows:
-    if (in_use + mac_data.entries <= MAC_TABLE_ENTRIES) {

however, as mac_data.entries is uint32_t, this sum
can overflow, e.g. if in_use is 1 and mac_data.entries
is 0xffffffff then in_use + mac_data.entries will be 0.

Qemu will then read guest supplied buffer into this
memory, overflowing buffer on heap.

MacOSX clang silently swallows unrecognized -f options when doing a link
with '-framework' also on the command line, so to detect support for
the various -fstack-protector options we must do a plain .c to .o compile,
not a complete compile-and-link.

Peter Maydell 7dc176bce4 hw/pci-host/prep: Don't reverse IO accesses on bigendian hosts
The raven_io_read() and raven_io_write() functions pass and
return values in little-endian format (since the IO op struct
is marked DEVICE_LITTLE_ENDIAN); however they were storing the
values in the buffer to pass to address_space_read/write()
in host-endian order, which meant that on big-endian hosts
the values were inadvertently reversed. Use the *_le_p()
accessors instead so that we are consistent regardless of
host endianness.

Strictly speaking the byte order of the buffer for
address_space_rw() is target byte order (which for PPC
will be BE) but it doesn't actually matter as long as we
are consistent about the marking on the IO op struct and
which stl_*_p().

This bug was probably introduced due to confusion caused by
the two different versions of ldl_p() and friends:
 bswap.h defines versions meaning "host endianness access"
 cpu-all.h defines versions meaning "target endianness access"
As a target-independent source file prep.c gets the bswap.h
versions; the very similar looking code in ioport.c is
compiled per-target and gets the cpu-all.h versions.

Takashi Iwai 800b0e814b gtk: Implement grab-on-click behavior in relative mode
This patch changes the behavior in the relative mode to be compatible
with other UIs, namely, grabbing the input at the first left click.
It improves the usability a lot; otherwise you have to press ctl-alt-G
or select from menu at each time you want to move the pointer.  Also,
the input grab is cleared when the current mode is switched to the
absolute mode.

The automatic reset of the implicit grabbing is needed since the
switching to the absolute mode happens always after the click even on
Gtk.  That is, we cannot check whether the absolute mode is already
available at the first click time even though it should have been
switched in X11 input driver side.
