Debian DLA-917-1 : rtmpdump security update

critical Nessus Plugin ID 99674

Synopsis

The remote Debian host is missing a security update.

Description

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.

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

Solution

Upgrade the affected librtmp-dev, librtmp0, and rtmpdump packages.
