-Date: Wed, 6 May 2015 09:48:59 +0200
-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] slirp: use less predictable directory name in /tmp for smb
- config (CVE-2015-4037)
-
-In this version I used mkdtemp(3) which is:
-
-        _BSD_SOURCE
-        || /* Since glibc 2.10: */
-            (_POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700)
-
-(POSIX.1-2008), so should be available on systems we care about.
-
-While at it, reset the resulting directory name within smb structure
-on error so cleanup function wont try to remove directory which we
-failed to create.
-

-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.

-Subject: [PATCH 3/3] ide: Clear DRQ after handling all expected accesses
-
-This is additional hardening against an end_transfer_func that fails to
-clear the DRQ status bit. The bit must be unset as soon as the PIO
-transfer has completed, so it's better to do this in a central place
-instead of duplicating the code in all commands (and forgetting it in
-some).
