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

Workaround

There is no known workaround at this time.

Resolution

All RTMPDump users should upgrade to the latest version:

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