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"
