Ubuntu Security Notice USN-3283-1

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 versions:
Ubuntu 16.04 LTS:
librtmp1 2.4+20151223.gitfa8646d-1ubuntu0.1
Ubuntu 14.04 LTS:
librtmp0 2.4+20121230.gitdf6c518-1ubuntu0.1
In general, a standard system update will make all the necessary changes.
