Started testing that the security fix will build everywhere on
release day. This is being particularly painful for the android build,
which has very old libraries and needed http-client updated, with many
follow-on changes, and is not successfully building yet after 5 hours.
I really need to finish deprecating the android build.
Pretty exhausted from all this, and thinking what to do about
external special remotes, I elaborated on an idea that Daniel Dent had
raised in discussions about vulnerability, and realized that git-annex
has a second, worse vulnerability. This new one could be used to trick a
git-annex user into decrypting gpg encrypted data that they had
never stored in git-annex. The attacker needs to have control of both an
encrypted special remote and a git remote, so it's not an easy exploit to
pull off, but it's still super bad.
This week is going to be a lot longer than I thought, and it's already
feeling kind of endless..
