PDF_JP2_BOX_ANOMALY
What it means
Embedded JP2/JPEG2000 data has invalid, oversized, or truncated box sizes.
Why it fires
Malformed JP2 boxes demonstrate invalid JPEG2000 structure; a bare /JPXDecode filter only identifies use of the codec. The malformed boxes do not establish a specific CVE such as CVE-2018-4990. The rule matches JP2 box lengths statically and flags impossible or truncated structures.
