Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 11.0.13, 17.0.1; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, 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 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 can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

dbcve analysis · high confidence

Vulnerability in Oracle Java SE and GraalVM Enterprise Edition Libraries component allows unauthenticated remote attackers to cause a partial denial of service (availability impact) via network access. The vulnerability affects Java deployments running sandboxed applets or Web Start applications, or code using the affected APIs.

MitigationApply Oracle security patches to update Oracle Java SE beyond 11.0.13/17.0.1 and Oracle GraalVM Enterprise Edition beyond 20.3.4/21.3.0 to the latest supported versions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Java version
    Run 'java -version' or 'java -fullversion' to obtain the exact version string. For Oracle JDK/JRE, also check the 'java.version' property via 'java -XshowSettings:all -version 2>&1 | grep version'. On Debian/Fedora, use package manager commands like 'dpkg -l | grep openjdk' or 'rpm -qa | grep openjdk'.
    Affected if The version matches Oracle OpenJDK 11.0.13 or earlier in the 11.x line, 13.0.9 or earlier in 13.x, 15.0.5 or earlier in 15.x, 7u321/7u331 or earlier in 7.x, 8u311/8u321 or earlier in 8.x, 17.0.1 or earlier in 17.x; or Oracle JDK/JRE 11.0.13 or 17.0.1; or Oracle GraalVM 20.3.4 or 21.3.0.
  2. Confirm Java vendor and build type
    Run 'java -version' and note the vendor line (Oracle OpenJDK, Oracle JDK, Oracle JRE, or check if it's from Debian/Fedora packages). Oracle-specific builds are affected; some downstream builds may differ.
    Affected if The output shows Oracle OpenJDK, Oracle JDK, or Oracle JRE versions matching the affected versions listed, or Debian packages version 11.0.13-2+deb11u1 or earlier, or Fedora 34 packages.
  3. Determine if sandboxed applets or Web Start are in use
    Search application codebases for 'Applet' class imports, '<applet>' tags in JNLP or HTML, or 'jnlp' file extensions. Check for 'javax.jnlp' API usage. List any deployed .jnlp or .jar files configured for web launch.
    Affected if The environment runs or loads sandboxed Java applets via the Java Plugin or Java Web Start applications using the deprecated plugin architecture.
  4. Identify usage of affected Libraries APIs
    Review application dependencies and source code for usage of the vulnerable 'Libraries' component APIs. Check if the application performs specific network operations or uses serialization features within the affected code path. Use 'java -verbose:class' during runtime to load classes from the libraries component.
    Affected if Code explicitly invokes APIs within the Oracle Java SE Libraries component that are known to handle the vulnerable network access codepath, particularly in contexts where network I/O occurs without full privilege separation.

You are affected if your Java installation version falls within the affected ranges (11.0.13 or earlier, 13.0.9 or earlier, 15.0.5 or earlier, 7u, 8u, 17.0.1, or GraalVM 20.3.4/21.3.0) AND your deployment runs sandboxed applets, Web Start applications, or code that directly uses the vulnerable Libraries component APIs exposed to network access.

dbcve · scoped
Upgrade available Upgrade to a release after 15.0.5
Interim mitigation

Apply Oracle security patches to update Oracle Java SE beyond 11.0.13/17.0.1 and Oracle GraalVM Enterprise Edition beyond 20.3.4/21.3.0 to the latest supported versions.

Recommended fix High confidence

OpenJDK 11.0.14 or later / OpenJDK 17.0.2 or later / Oracle Java SE 11.0.14+ or 17.0.2+

  1. Identify the exact Java/OpenJDK/JRE version currently installed using 'java -version' or checking /usr/lib/jvm/
  2. For Debian systems: Run 'apt-get update' and 'apt-get install openjdk-11-jdk' or 'openjdk-17-jdk' to upgrade to the latest available version in the repository
  3. For Fedora systems: Run 'dnf update java-11-openjdk' or 'dnf update java-17-openjdk'
  4. Verify the upgrade was successful by running 'java -version' again
  5. Ensure any applications or services relying on Java are restarted after the upgrade
Caveat Major version upgrades (e.g., 11 to 17) may require code changes due to language/behavior differences; test thoroughly before production deployment
