Technical details

The vulnerabilities stem from improper resource handling and input validation in the Content Credentials Rust SDK, C2PA Tool, and JavaScript SDK, allowing attackers to exhaust system resources via network requests without authentication. Several issues involve uncontrolled resource consumption (CWE-400) and integer overflow (CWE-190) leading to application denial-of-service. Fixes are available in c2pa v0.91.1, c2patool v0.28.1, and @contentauth/c2pa-web v0.15.3.
