"statement": "Red Hat has rated this vulnerability as Critical because remote unauthenticated attackers can bypass file inspection controls and overwrite arbitrary system files, potentially achieving arbitrary code execution without requiring user interaction. In automated ingestion pipelines or services handling user-supplied archives, discrepancies between how headers are processed allow malicious files to masquerade under harmless names during gateway validation while extracting dangerous payloads to target directories. The overall impact depends on whether affected applications process untrusted inputs using sequential extraction routines and run with sufficient system privileges to overwrite sensitive operational files.", "threat_severity": "Critical"}
