The AMF3CD_AddProp function in amf.c in RTMPDump 2.4 allows remote RTMP Media servers to execute arbitrary code.

Dave McDaniel discovered that rtmpdump incorrectly handled certain malformed streams. If a user were tricked into processing a specially crafted stream, a remote attacker could cause rtmpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Dave McDaniel discovered multiple vulnerabilities in rtmpdump, a small dumper/library for RTMP media streams, which may result in denial of service or the execution of arbitrary code if a malformed stream is dumped.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3283-1 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities were found in rtmpdump and the librtmp library.

CVE-2015-8270

A bug in AMF3ReadString in librtmp can cause a denial of service via application crash to librtmp users that talk to a malicious server.

CVE-2015-8271

The AMF3_Decode function in librtmp doesn't properly validate its input, which can lead to arbitrary code execution when talking to a malicious attacker.

CVE-2015-8272

A bug in rtmpsrv can lead to a crash when talking to a malicious client.

For Debian 7 'Wheezy', these problems have been fixed in version 2.4+20111222.git4e06e21-1+deb7u1.

We recommend that you upgrade your rtmpdump packages.
