[sup-talk] Security advisory, releases 0.13.2.1 and 0.14.1.1

[Gaute Hope]

Greetings,

Security advisory (#SBU1) for Sup

We have been notified of an potential exploit in the somewhat careless
way Sup treats attachment metadata in received e-mails. The issues
should now be fixed and I have released Sup 0.13.2.1 and 0.14.1.1 which
incorporates these fixes. Please upgrade immediately and also ensure
that your mime-decode or mime-view hooks are secure [0], [1].

This is specifically related to using quotes (',") around filename or
content_type which is already escaped using Ruby Shellwords.escape -
this means that the string (content_type, filename) is intended to be
used _without_ any further quotes. Please make sure that if you use
.mailcap (non OSX systems), you do not quote the string.

discovered and suggested fixes for these issues.
