git-annex checksum exposure to encrypted special remotes
Details

git-annex checksum exposure to encrypted special remotes

A bug exposed the checksum of annexed files to encrypted special remotes, which are not supposed to have access to the checksum of the un-encrypted file. This only occurred when resuming uploads to the encrypted special remote, so it is considered a low-severity security hole.

For details, see commit b890f3a53d936b5e40aa9acc5876cb98f18b9657.

No CVE was assigned for this issue.

Fixed in git-annex-6.20160419.
