git-annex private data exfiltration to compromised remote

CVE-2018-10857 git-annex private data exfiltration to compromised remote
git-annex private data exfiltration to compromised remote
# *git-annex* private data exfiltration to compromised remote
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. Joey Hess discovered
this attack.
To perform this attack, the attacker needs to have control over one
of the remotes of the victim's *git-annex* repository. For example,
they may provide a public *git-annex* repository that the victim
clones. Or, equivalantly, the attacker could have read access to the
victim's *git-annex* repository or a repository it pushes to, and
some channel to get commits into it (e.g. pull requests).

git-annex GPG decryption attack via compromised remote

CVE-2018-10859 [HIGH] git-annex GPG decryption attack via compromised remote
git-annex GPG decryption attack via compromised remote
# *git-annex* GPG decryption attack via compromised remote
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*. Daniel Dent discovered this attack in collaboration
with Joey Hess.
To perform this attack the attacker needs control of a server
hosting an *encrypted* special remote used by the victim's
*git-annex* repository. The attacker uses `git annex addurl
--relaxed` with an innocuous URL, and waits for the user's
`git-annex` to download it, and upload an (encrypted) copy to the
special remote they also control. At some later point, when the
user downloads the content
