-Subject: [PATCH] fdc: force the fifo access to be in bounds of the allocated
- buffer
-
-During processing of certain commands such as FD_CMD_READ_ID and
-FD_CMD_DRIVE_SPECIFICATION_COMMAND the fifo memory access could
-get out of bounds leading to memory corruption with values coming
-from the guest.
-
-Fix this by making sure that the index is always bounded by the
-allocated memory.
-
-This is CVE-2015-3456.

-Subject: [PATCH 1/3] ide: Check array bounds before writing to io_buffer
- (CVE-2015-5154)
-
-If the end_transfer_func of a command is called because enough data has
-been read or written for the current PIO transfer, and it fails to
-correctly call the command completion functions, the DRQ bit in the
-status register and s->end_transfer_func may remain set. This allows the
-guest to access further bytes in s->io_buffer beyond s->data_end, and
-eventually overflowing the io_buffer.
-
-One case where this currently happens is emulation of the ATAPI command
-START STOP UNIT.
-
-This patch fixes the problem by adding explicit array bounds checks
-before accessing the buffer instead of relying on end_transfer_func to
-function correctly.

- scsi: fix buffer overflow in scsi_req_parse_cdb (CVE-2015-5158)
-
- This is a guest-triggerable buffer overflow present in QEMU 2.2.0
- and newer. scsi_cdb_length returns -1 as an error value, but the
- caller does not check it.
-
- Luckily, the massive overflow means that QEMU will just SIGSEGV,
- making the impact much smaller.
