rclone selfupdate checked the PGP signature on the clearsigned block of SHA256SUMS but then looked up the archive hash in the whole downloaded file. Unsigned data can appear in that file without invalidating the signature. A hash line placed before or after the signed text was accepted, allowing whoever controlled the download to install an arbitrary unsigned archive. The hash is now only looked up in the signed text. Affects stable (non --beta) selfupdate since v1.55.0. --beta updates are not signature checked.
