Summary
openjdk-17 vulnerabilities
Details

It was discovered that the RMI component of OpenJDK 17 would establish RMI TCP endpoint connections to a remote host without setting an endpoint identification algorithm. An unauthenticated remote attacker could possibly use this issue to steal sensitive information. (CVE-2026-21925)

Mingijung discovered that the AWT and JavaFX componenets of OpenJDK 17 could run programs if Desktop.browse() was supplied a filename as a URI. An unauthenticated remote attacker could possibly use this issue to execute arbitrary code. (CVE-2026-21932)

Zhihui Chen discovered that the Networking component of OpenJDK 17 was suceptible to a CRLF injection vulnerability via the HttpServer class. An unauthenticated remote attacker could possibly use this issue to modify files or leak sensitive information. (CVE-2026-21933)

Ireneusz Pastusiak discovered that the Security component of OpenJDK 17 failed to verify provided URIs point to a legitimate source when AIA is enabled. An unauthenticated remote attacker could possibly use this issue to redirect users to malicious hosts. (CVE-2026-21945)

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.
