Description
===========

- CVE-2018-10857 (arbitrary filesystem access)

Some uses of git-annex were vulnerable to a private data exposure and
exfiltration attack. It could expose the content of files located
outside the git-annex repository, or content from a private web server
on localhost or the LAN.

- CVE-2018-10859 (information disclosure)

A malicious server for a special remote could trick git-annex into
decrypting a file that was encrypted to the user's gpg key. This attack
could be used to expose encrypted data that was never stored in git-
annex

Impact
======

A remote attacker is able to read arbitrary files on the filesystem or
decrypt encrypted files by modifying the git-annex repository.
