Ubuntu Security Notice USN-3283-2

23rd May, 2017

rtmpdump vulnerabilities

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

  • Ubuntu 12.04 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 12.04 LTS:
librtmp0 2.4~20110711.gitc28f1bab-1ubuntu0.1

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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