+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.

+ 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.

+
+USB Ehci emulation supports host controller capability registers.
+But its mmio '.write' function was missing, which lead to a null
+pointer dereference issue. Add a do nothing 'ehci_caps_write'
+definition to avoid it; Do nothing because capability registers
+are Read Only(RO).

+
+When processing remote NDIS control message packets, the USB Net

+object is of RNDIS type(2). But it does not check if it is null,
+which leads to a null dereference error. Add check to avoid it.

+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.

+Subject: [PATCH] usb: check RNDIS buffer offsets & length
+
+When processing remote NDIS control message packets,
+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.
