Summary
======
The package wireshark-gtk before version 2.2.2-1 is vulnerable to
multiple issues including arbitrary code execution and denial of
service.

Resolution
=========
Upgrade to 2.2.2-1.

# pacman -Syu "wireshark-gtk>=2.2.2-1"

The problems have been fixed upstream in version 2.2.2.

Workaround
=========
None.

Description
==========
- CVE-2016-9373 (arbitrary code execution)

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DCERPC dissector
could crash with a use-after-free, triggered by network traffic or a
capture file. This was addressed in epan/dissectors/packet-dcerpc-nt.c
and epan/dissectors/packet-dcerpc-spoolss.c by using the wmem file
scope for private strings.

- CVE-2016-9374 (denial of service)

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the AllJoyn dissector
could crash with a buffer over-read, triggered by network traffic or a
capture file. This was addressed in epan/dissectors/packet-alljoyn.c by
ensuring that a length variable properly tracked the state of a
signature variable.

- CVE-2016-9375 (denial of service)

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DTN dissector could
go into an infinite loop, triggered by network traffic or a capture
file. This was addressed in epan/dissectors/packet-dtn.c by checking
whether SDNV evaluation was successful.

- CVE-2016-9376 (denial of service)

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the OpenFlow dissector
could crash with memory exhaustion, triggered by network traffic or a
capture file. This was addressed in epan/dissectors/packet-openflow_v5.c by ensuring that certain length values were sufficiently
large.

Impact
=====
A remote attacker is able to execute arbitrary code or perform a denial
of service attack via malicious network traffic.
