[Bug 1409117] Re: GPG does not verify keys received when using --recv-keys leaving communicaiton with key servers vulnerable to MITM

 

apt-add-repository validates that the key that was downloaded is the
right one before importing it, it doesn't blindly trust the key that gpg
downloaded from the keyserver.

This is wishlist simply because it's security hardening. I will include
it in the next gnupg security upload.

Bug description:
  The patch from http://bugs.gnupg.org/gnupg/issue1579 is critical and
  should be backported to 12.04; right now, it is not.

  This leaves 12.04 users of GPG2 vulnerable to MITM attacks on gpg2
  --recv-keys. See https://evil32.com/ for an example (the text that is
  striked out; the gpg2 package on 12.04 is still vulnerable).
