Description
===========

- CVE-2014-8710 (out-of-bounds read)
Out-of-bounds read flaw in the SigComp dissector (sigcomp-udvm) leads to
denial of service while processing malformed packets.

- CVE-2014-8711 (out-of-bounds read)
The AMQP dissector is seeing a large value in the capture file for what
it thinks should be a field specifying the number of elements in an
array, resulting in undetected overflow (wrapping).

- CVE-2014-8712 (stack buffer overflow)
An issue in the NCP dissector while constructing strings may lead to
incorrect data length, resulting in stack buffer overflow and denial of
service.

- CVE-2014-8713 (denial of service)
An issue in the NCP dissector may lead to denial of service while
accessing an uninitialized buffer.

- CVE-2014-8714 (denial of service)
A missing exit when the offset is not incremented in the tn5250
dissector is leading to an endless loop, resulting in denial of service.

Impact
======

It may be possible to make wireshark crash by injecting a malformed
packet onto the wire or by convincing someone to read a malformed packet
trace file.
