Bug#929167: apt: Failed to confirm additional package to be installed (Ref: curl)



Package: apt
Version: 1.8.1
Severity: important

Dear Maintainer(s),

Hi! #ThankYou for all the work you all do! Once I found the apt-get/apt command line family method of managing Debian packages, I've never looked back since.

Why I'm writing: Odd glitch this morning. While *attempting* to read through and comprehend the current reportbug APT buglist entries before sending this, it occurred to me that this glitch could potentially be abused if someone figured out how it occurred. I've marked this bug as "important", but... I feel it's possibly a security risk on some level...

So what had happened was: This morning, I ran "apt upgrade" (which is occasionally alternated with apt-get purely because that's where my Fingertips go).

I'm on dialup so I have to cherry pick what packages get upgraded in between any other online computing. This morning I started with "curl".

Curl needed two packages to install. Those packages only added up to 595KB download size, but THAT FAILED *because* of dialup. That's the GOOD NEWS because it provided the opportunity to witness the following issue..

Run #1 began like this:

+++++ START APT FEEDBACK FOR RUN #1 +++++

The following additional packages will be installed:
  libcurl4
The following packages will be upgraded:
  curl libcurl4
2 upgraded, 0 newly installed, 0 to remove and 19 not upgraded.
Need to get 595 kB of archives.
After this operation, 0 B of additional disk space will be used.
Get:1 http://distro.ibiblio.org/debian buster/main amd64 curl amd64 7.64.0-3 [264 kB]

+++++ END APT FEEDBACK FOR RUN #1 +++++

Boom, right into the download process without asking after encountering a secondary package that needed to be simultaneously installed. APT completely skipped over the *expected* "Do you want to continue? [Y/n]" line which SHOULD HAVE been triggered by APT needing to install that additional "libcurl4" package. APT instead immediately began the "curl/libcurl4" package combination upgrade without further intervention from me.

On the second run that was necessary because the dialup connection failed, APT reverted back to the expected behavior for that SAME package, i.e.: 

+++++ START APT FEEDBACK FOR RUN #2 +++++

The following additional packages will be installed:
  libcurl4
The following packages will be upgraded:
  curl libcurl4
2 upgraded, 0 newly installed, 0 to remove and 19 not upgraded.
Need to get 331 kB/595 kB of archives.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] 

+++++ END APT FEEDBACK FOR RUN #2 +++++

The real time outcome of what occurred is that APT caught itself in Run #2 and recovered thus reverting back to its expected behavior as usual. That expected behavior is where it asks first before forging ahead with the installation of more necessary dependency or primary packages than users initially enter on the command line.

A "conspiracy leaning" outcome of what occurred would potentially be: If someone figures out how to maliciously trigger that behavior via a package not directly under Debian Developers' scrutiny, there is *THEORETICALLY* a chance that behavior could be abused to infiltrate a potentially vulnerable system.

As for me, I ALWAYS look at what apt/apt-get's additionally installing just to make sure all packages are recognizable as familiar k/t years of having to upgrade via this manual method. New users and very busy seasoned users using much faster network connections don't always have that.. *cough*.. LUXURY. :)

That's pretty much all I can think of to fill in. Thank you all again for what became a very user-friendly method of maintaining Debian once I got over the *fear* of doing anything via Linux command line.

Afterthought: For anyone who stumbles upon this and has not yet done so, I highly recommend at least test-driving that route by working with a very simple package (and the guidance of your favorite user support list). APT's a very *EMPOWERING* alternative once you get the hang of it! :)
