Summary

Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition (component: 2D) in multiple versions have a difficult-to-exploit vulnerability that allows an unauthenticated attacker with network access to cause a partial denial of service (partial DOS). This vulnerability primarily affects clients running Java Web Start applets.

Risk Assessment

An attacker can cause partial downtime of Java applications, affecting service availability for end users.

Recommendation

Update Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition to the latest versions and restrict execution of untrusted Java code.

Original NVD description (English source)

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
