Upgrade exiftool to 12.24 or above
The current version of exiftool installed in Tails 5.9, exiftool 12.16, is within the version range for a vulnerability related to parsing malicious files (CVE-2021-22204). I recommend upgrading exiftool to 12.24 or above (not sure if this is more of Debian issue than a Tails one, given the package source, but figure I'd make an issue for it here first).
