USN-3283-1: rtmpdump vulnerabilities

9 May 2017

rtmpdump vulnerabilities

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

  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS


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


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 versions:

Ubuntu 16.04 LTS
librtmp1 - 2.4+20151223.gitfa8646d-1ubuntu0.1
Ubuntu 14.04 LTS
librtmp0 - 2.4+20121230.gitdf6c518-1ubuntu0.1
