Subject: [PATCH] scsi: initialise info object with appropriate size
While processing controller 'CTRL_GET_INFO' command, the routine
'megasas_ctrl_get_info' overflows the '&info' object size. Use its
appropriate size to null initialise it.

Subject: [PATCH] hmp: fix sendkey out of bounds write (CVE-2015-8619)
When processing 'sendkey' command, hmp_sendkey routine null
terminates the 'keyname_buf' array. This results in an OOB
write issue, if 'keyname_len' was to fall outside of
'keyname_buf' array.
Since the keyname's length is known the keyname_buf can be
removed altogether by adding a length parameter to
index_from_key() and using it for the error output as well.

Subject: [PATCH] fw_cfg: avoid calculating invalid current entry pointer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When calculating a pointer to the currently selected fw_cfg item, the
following is used:
FWCfgEntry *e = &s->entries[arch][s->cur_entry & FW_CFG_ENTRY_MASK];
When s->cur_entry is FW_CFG_INVALID, we are calculating the address of
a non-existent element in s->entries[arch][...], which is undefined.
This patch ensures the resulting entry pointer is set to NULL whenever
s->cur_entry is FW_CFG_INVALID.

Subject: [PATCH] i386: avoid null pointer dereference
Hello,
A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
occurs while doing I/O port write operations via hmp interface. In that,
'current_cpu' remains null as it is not called from cpu_exec loop, which
results in the said issue.
Below is a proposed (tested)patch to fix this issue; Does it look okay?

Subject: [PATCH] e1000: eliminate infinite loops on out-of-bounds transfer
start
The start_xmit() and e1000_receive_iov() functions implement DMA transfers
iterating over a set of descriptors that the guest's e1000 driver
prepares:
- the TDLEN and RDLEN registers store the total size of the descriptor
area,
- while the TDH and RDH registers store the offset (in whole tx / rx
descriptors) into the area where the transfer is supposed to start.
Each time a descriptor is processed, the TDH and RDH register is bumped
(as appropriate for the transfer direction).
QEMU already contains logic to deal with bogus transfers submitted by the
guest:
- Normally, the transmit case wants to increase TDH from its initial value
to TDT. (TDT is allowed to be numerically smaller than the initial TDH
value; wrapping at or above TDLEN bytes to zero is normal.) The failsafe
that QEMU currently has here is a check against reaching the original
TDH value again -- a complete wraparound, which should never happen.
- In the receive case RDH is increased from its initial value until
"total_size" bytes have been received; preferably in a single step, or
in "s->rxbuf_size" byte steps, if the latter is smaller. However, null
RX descriptors are skipped without receiving data, while RDH is
incremented just the same. QEMU tries to prevent an infinite loop
(processing only null RX descriptors) by detecting whether RDH assumes
its original value during the loop. (Again, wrapping from RDLEN to 0 is
normal.)
What both directions miss is that the guest could program TDLEN and RDLEN
so low, and the initial TDH and RDH so high, that these registers will
immediately be truncated to zero, and then never reassume their initial
values in the loop -- a full wraparound will never occur.
The condition that expresses this is:
xdh_start >= s->mac_reg[XDLEN] / sizeof(desc)
i.e., TDH or RDH start out after the last whole rx or tx descriptor that
fits into the TDLEN or RDLEN sized area.
This condition could be checked before we enter the loops, but
pci_dma_read() / pci_dma_write() knows how to fill in buffers safely for
bogus DMA addresses, so we just extend the existing failsafes with the
above condition.
This is CVE-2016-1981.

Subject: [PATCH] rng: add request queue support to rng-random
Requests are now created in the RngBackend parent class and the
code path is shared by both rng-egd and rng-random.
This commit fixes the rng-random implementation which processed
only one request at a time and simply discarded all but the most
recent one. In the guest this manifested as delayed completion
of reads from virtio-rng, i.e. a read was completed only after
another read was issued.
By switching rng-random to use the same request queue as rng-egd,
the unsafe stack-based allocation of the entropy buffer is
eliminated and replaced with g_malloc.

the USB Net device emulator uses a fixed length(4096) data buffer.
The incoming informationBufferOffset & Length combination could
overflow and cross that range. Check control message buffer
offsets and length to avoid it.
