Overview
Affected versions of this package are vulnerable to Out-of-bounds Read through improper bounds checking in the CreateInstanceFromBackup and CreateInstanceFromMigration functions. An attacker can cause the daemon to crash by submitting a crafted backup archive with physical snapshot directories and a tampered metadata array, resulting in a denial of service.
