simplestreams vulnerability

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

- Ubuntu 15.04
- Ubuntu 14.04 LTS


Applications using Simple Streams could be made to crash or run
programs if it received specially crafted network traffic.

Software Description:

It was discovered that Simple Streams did not properly perform gpg
verification in some situations. A remote attacker could use this to
perform a man-in-the-middle attack and inject malicious content into
the stream.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.04:
