USN-3283-1: rtmpdump vulnerabilities
Ubuntu Security Notice USN-3283-1
9th May, 2017
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.
- 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.
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: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
