N/A - GLSA-201702-02

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

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"
