CVE-2022-21365Network attack vector

Service interruption via undisclosed ImageIO flaw

Published Jan 19, 2022 · Updated Nov 19, 2024

Denial of service in affected Oracle Java SE and GraalVM ImageIO versions allows remote attackers to interrupt Java deployments. Oracle has not disclosed the faulty ImageIO operation or the untrusted input form that triggers the availability loss. Exposure requires a deployment that passes untrusted content to ImageIO, such as sandboxed client code or a network service using its APIs.
