Subject: [cryptography] chromium: unconditionally downloads binary

After upgrading chromium to 43, I noticed that when it is running and
immediately after the machine is on-line it silently starts
downloading "Chrome Hotword Shared Module" extension, which contains a
binary without source code. There seems no opt-out config.
that extension:
- doesn't appear in the extension list;
- is apparently used to provide an “ok google” voice activation stuff.
The fact that Audio Capture Allowed is set to yes, and that both the
extension and the shared module are marked as “enabled” are definitely
bothering me.
I didn't see that, didn't even look, but theres enough rumors floating
around that I called up synaptic 2 days ago, and nuked it all with
extreme prejudice. I hope that got it all.
What has been the experience of others in a successful removal of it and
all its sneaky stuffs?

We believe that the bug you reported is fixed in the latest version of
chromium-browser, which is due to be installed in the Debian FTP
archive.

Shouldn't we see a DSA [Debian Security Advisory] following this
incident?
Since no one really know which binaries have been downloaded there and
what they actually do, and since it cannot be excluded that it was
actually executed, such systems are basically to be considered
compromised.
Quite a deal of people choose open source just to prevent that - get
untrustworthy / unverifiable code run on their systems - failed.

Thank you for the heads up! It's disconcerting that Debian did not issue
a security advisory on this one, though somewhat understandable. Perhaps
we need both "security advisories" and "privacy advisories" these
days?
