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

- Ubuntu 12.04 ESM

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 12.04 ESM:
  librtmp0                        2.4~20110711.gitc28f1bab-1ubuntu0.1

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