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

- CVE-2018-12086 (arbitrary code execution)

A flaw has been discovered in wireshark >= 2.6.0 and < 2.6.4 in the
OpcUa dissector where a specially crafted structured request could lead
to stack overflow. This could be used by an attacker to crash wireshark
or execute arbitrary code on the affected host by injecting a malformed
packet onto the wire or by convincing someone to read a malformed
packet trace file.

- CVE-2018-18225 (denial of service)

A flaw has been discovered in wireshark >= 2.6.0 and < 2.6.4 in the
CoAP dissector where an invalid frame could lead to NULL-pointer
dereference. This could be used by an attacker to crash wireshark by
injecting a malformed packet onto the wire or by convincing someone to
read a malformed packet trace file.

- CVE-2018-18226 (denial of service)

A flaw has been discovered in wireshark >= 2.6.0 and < 2.6.4 in the
Steam IHS Discovery dissector where dynamically allocated memory was
not properly freed on exception. This could be used by an attacker to
crash wireshark by injecting a malformed packet onto the wire or by
convincing someone to read a malformed packet trace file.

- CVE-2018-18227 (denial of service)

A flaw has been discovered in wireshark >= 2.6.0 and < 2.6.4 in the
MS-WSP dissector where an invalid type could lead to an assertion
failure. This could be used by an attacker to crash wireshark by
injecting a malformed packet onto the wire or by convincing someone to
read a malformed packet trace file.

Impact
======

An attacker can crash wireshark or execute arbitrary code on the
affected host by injecting a malformed packet onto the wire or by
convincing a local user to read a malformed packet trace file.
