**Name of the Vulnerable Software and Affected Versions** Oracle Java SE versions 11.0.17, 17.0.5, 19.0.1 Oracle GraalVM Enterprise Edition versions 20.3.8, 21.3.4, 22.3.0 **Description** The issue is related to an easily exploitable vulnerability in the JSSE component of Oracle Java SE and Oracle GraalVM Enterprise Edition. This vulnerability allows an unauthenticated attacker with network access via DTLS to compromise the system, resulting in a partial denial of service. The vulnerability applies to Java deployments that load and run untrusted code, such as sandboxed Java Web Start applications or sandboxed Java applets, and rely on the Java sandbox for security. **Recommendations** For Oracle Java SE versions 11.0.17, 17.0.5, 19.0.1, update to a newer version that contains a fix for this issue. For Oracle GraalVM Enterprise Edition versions 20.3.8, 21.3.4, 22.3.0, update to a newer version that contains a fix for this issue. As a temporary workaround, consider restricting access to the DTLS protocol to minimize the risk of exploitation. Note: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
