Overview
Affected versions of this package are vulnerable to Cryptographic Operations are run Before Supporting Units are Ready due to a flaw in the cryptographic authentication scheme. An attacker can fake archives and potentially indirectly cause backup data loss in the repository by inserting files (with no additional headers) into backups and gaining write access to the repository.
Note:
Data loss after being attacked can be avoided by reviewing the archives (timestamp and contents valid and as expected) after any "borg check --repair" and before "borg prune".
