Subject: [PATCH] pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.
Fix this by only allowing to queue maximum sizeof(buffer) bytes.
This is CVE-2015-3209.
[Fixed 3-space indentation to QEMU's 4-space coding standard.

X-Git-Tag: v2.4.0-rc0~43^2~9
X-Git-Url: http://git.qemu.org/?p=qemu.git;a=commitdiff_plain;h=d4862a87e31a51de9eb260f25c9e99a75efe3235;hp=9dacf32d2cbd66cbcce7944ebdfd6b2df20e33b8
i8254: fix out-of-bounds memory access in pit_ioport_read()
Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.
Fix this by ignoring read from the Mode/Command register.
This is CVE-2015-3214.

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] 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] 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).

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.

Transmit offload needs to parse packet headers. If header fields have
unexpected values the offload processing is skipped.
The code currently uses nested ifs because there is relatively little
input validation. The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.
