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: ImageIO). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 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).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

CVE-2022-21365 is an ImageIO component vulnerability in Oracle Java SE (versions 7u321, 8u311, 11.0.13, 17.0.1) and Oracle GraalVM Enterprise Edition (20.3.4, 21.3.0). The flaw allows unauthenticated remote attackers to cause a partial denial of service via specially crafted image data processed through ImageIO APIs, typically exploitable through sandboxed Java Web Start applications or applets loading untrusted code from the internet.

MitigationApply Oracle's Critical Patch Update (CPU) for affected Java versions. For deployments using sandboxed code execution, ensure the Java sandbox security restrictions remain enforced and consider restricting network access to untrusted endpoints.

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 Java installation and version
    Run 'java -version' or 'java -fullversion' from command line to obtain the installed Java version string
    Affected if The reported version matches any of the affected versions: 7u321, 8u311, 11.0.13, 17.0.1, or falls within the ranges >= 11 <= 11.0.13, >= 13 <= 13.0.9, >= 15 <= 15.0.5, or version 17 for Oracle OpenJDK; or versions 20.3.4, 21.3.0 for GraalVM; or 1.7.0, 1.8.0 for JDK/JRE
  2. Confirm ImageIO component is accessible
    Verify the Java installation includes the javax.imageio package by checking if ImageIO classes are available: 'java javax.imageio.ImageIO' or inspect the JAR file for imageio classes
    Affected if ImageIO classes are present in the Java installation and the version is among the affected versions
  3. Determine if application processes untrusted image data
    Review application code or configuration for usage of ImageIO read methods (ImageIO.read()) on data from untrusted sources such as network endpoints, user uploads, or web start/applet contexts
    Affected if The environment loads or processes image data from untrusted sources through ImageIO APIs, making it potentially exploitable
  4. Check if running in sandboxed execution context
    Inspect Java security policy settings and determine if code is running in sandboxed mode via Web Start, applets, or restricted security manager configurations
    Affected if The Java environment runs sandboxed code (Web Start applications or applets) loading untrusted images from the internet, which is the typical exploitation vector for this CVE

You are affected if your installed Java/JRE/JDK version matches the affected versions AND your application or sandboxed code processes untrusted image data through ImageIO APIs.

Upgrade available Upgrade to a release after 15.0.5
Interim mitigation

Apply Oracle's Critical Patch Update (CPU) for affected Java versions. For deployments using sandboxed code execution, ensure the Java sandbox security restrictions remain enforced and consider restricting network access to untrusted endpoints.

Recommended fix High confidence

Oracle Java SE 8u321+/11.0.14+/17.0.2+, OpenJDK 11.0.14+/17.0.2+, or GraalVM Enterprise Edition 20.3.5+/21.3.1+

  1. 1. Identify the exact Java/OpenJDK version installed by running 'java -version' or 'openjdk-version'
  2. 2. For Oracle Java SE: upgrade to Java SE 7u331 or later, 8u321 or later, 11.0.14 or later, or 17.0.2 or later
  3. 3. For OpenJDK: upgrade to OpenJDK 11.0.14 or later, 13.0.10 or later, 15.0.6 or later, or 17.0.2 or later
  4. 4. For Oracle GraalVM Enterprise Edition: upgrade to 20.3.5 or later, or 21.3.1 or later
  5. 5. Verify the upgrade was successful by running 'java -version' and confirming the new version number
  6. 6. Test application functionality to ensure compatibility with the new Java version
Caveat Minor update; however, test applications thoroughly as unexpected behavior changes can occur even in patch updates
