-Subject: [PATCH] ehci: make idt processing more robust
-
-Make ehci_process_itd return an error in case we didn't do any actual
-iso transfer because we've found no active transaction.  That'll avoid
-ehci happily run in circles forever if the guest builds a loop out of
-idts.

-This is CVE-2015-8558.

-Subject: [PATCH] net: vmxnet3: avoid memory leakage in activate_device
-
-Vmxnet3 device emulator does not check if the device is active
-before activating it, also it did not free the transmit & receive
-buffers while deactivating the device, thus resulting in memory
-leakage on the host. This patch fixes both these issues to avoid
-host memory leakage.

-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] ide: ahci: reset ncq object to unused on error
-
-When processing NCQ commands, AHCI device emulation prepares a
-NCQ transfer object; To which an aio control block(aiocb) object
-is assigned in 'execute_ncq_command'. In case, when the NCQ
-command is invalid, the 'aiocb' object is not assigned, and NCQ
-transfer object is left as 'used'. This leads to a use after
-free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
-Reset NCQ transfer object to 'unused' to avoid it.

-
-    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.
