Ubuntu Security Notice USN-3283-1

9th May, 2017

rtmpdump vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 16.04 LTS
• Ubuntu 14.04 LTS

Summary

rtmpdump could be made to crash or run programs as your login if it processed a specially crafted stream.

Software description

• rtmpdump - small dumper for media content streamed over the RTMP protocol

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package version:

Ubuntu 16.04 LTS:

librtmp1 2.4+20151223.gitfa8646d-1ubuntu0.1

Ubuntu 14.04 LTS:

librtmp0 2.4+20121230.gitdf6c518-1ubuntu0.1

To update your system, please follow these instructions: http://ift.tt/17VXqjU.

In general, a standard system update will make all the necessary changes.
