"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.
