Synopsis
========

Multiple vulnerabilities have been found in RTMPDump, the worst of
which could lead to arbitrary code execution.

Background
==========

RTMPDump is an RTMP client intended to stream audio or video flash
content

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-video/rtmpdump     < 2.4_p20161210        >= 2.4_p20161210

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

Multiple vulnerabilities have been discovered in RTMPDump.

The following is a list of vulnerabilities fixed:

* Additional decode input size checks
* Ignore zero-length packets
* Potential integer overflow in RTMPPacket_Alloc().
* Obsolete RTMPPacket_Free() call left over from original C++ to C
  rewrite
* AMFProp_GetObject must make sure the prop is actually an object

Impact
======

A remote attacker could entice a user to open a specially crafted media
flash file using RTMPDump. This could possibly result in the execution
of arbitrary code with the privileges of the process or a Denial of
Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All RTMPDump users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=media-video/rtmpdump-2.4_p20161210"
