    Several vulnerabilities have been discovered in the OpenJDK Java
    runtime, which may result in denial of service, information disclosure,
    unauthorized access or bypass of sandbox restrictions.

    For Debian 12 bookworm, these problems have been fixed in version
    17.0.21+9-1~deb12u1.

    We recommend that you upgrade your openjdk-17 packages.

    For the detailed security status of openjdk-17 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/openjdk-17
