This is affecting unstable and stable. oldstable is not affected.

I'll upload 1.4.16 (.1 due soon probably, since .16 has a major bug) to
unstable probably tomorrow or the day after that.

For stable, I don't think that the vulnerability is serious enough to
warrant a DSA. Maybe s-p-u is a better candidate?
