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: 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

dbcve analysis · high confidence

Vulnerability in Oracle Java SE and GraalVM Enterprise Edition's ImageIO component allows unauthenticated remote attackers to cause partial denial of service via specially crafted image files processed through the ImageIO API.

MitigationApply Oracle's Critical Patch Update containing the fix for this vulnerability by upgrading to a patched Java SE version (11.0.14+, 17.0.2+) or GraalVM Enterprise Edition version beyond 21.3.0.

Am I affected?

dbcve checks

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

Identify installed Java version

Run 'java -version' to obtain the Java runtime version and vendor information

Affected if Version is Oracle OpenJDK, Oracle JDK, or Oracle JRE 11.0.13 or earlier, 13.0.9 or earlier, 15.0.5 or earlier, or exactly 17 or 17.0.1
Check for GraalVM installation

Run 'java -version' or inspect system for GraalVM installation directories

Affected if GraalVM Enterprise Edition version 20.3.4 or 21.3.0 is installed
Identify ImageIO usage in application

Search application source code for imports of javax.imageio or usage of ImageIO.read() method, or inspect application for image processing libraries

Affected if Application code invokes the ImageIO API to process image files from untrusted sources
Check Debian system Java packages

On Debian systems, run 'dpkg -l | grep openjdk' or check installed packages via package manager

Affected if Debian Linux 10.0 or 11.0 with OpenJDK packages from affected versions are installed
Inspect NetApp product installations

Verify if NetApp 7 Mode Transition Tool, Active IQ Unified Manager, or Cloud Insights Acquisition Unit are installed

Affected if Any of these NetApp products are running (all versions are affected)

System is affected if running an affected Java/GraalVM version AND the application processes image files through the ImageIO API, or if running affected NetApp products.

Generated from the published advisory. Verify against your own configuration.

Remediation

dbcve · scoped

Upgrade available Upgrade to a release after 15.0.5

Interim mitigation

Apply Oracle's Critical Patch Update containing the fix for this vulnerability by upgrading to a patched Java SE version (11.0.14+, 17.0.2+) or GraalVM Enterprise Edition version beyond 21.3.0.

Recommended fix High confidence

Oracle Java SE 11.0.14+/17.0.2+; Oracle GraalVM Enterprise Edition 21.3.1+; Debian openjdk security updates

Identify the current Java/JDK/JRE version by running: java -version
For Oracle Java SE: Upgrade to Java SE 11.0.14 or higher, or 17.0.2 or higher
For OpenJDK: Upgrade to a version beyond 11.0.13, 13.0.9, 15.0.5, or apply vendor security updates
For Oracle GraalVM Enterprise Edition: Upgrade to version 21.3.1 or later (which includes the security fix)
For Debian systems: Run 'apt-get update && apt-get upgrade' to apply Debian security patches, or specifically upgrade the openjdk packages
Verify the fix by checking the updated version: java -version
Ensure any applications using the ImageIO API are restarted to use the patched JVM

Caveat Minor - this is a security patch upgrade; ensure compatibility with existing application code using ImageIO APIs

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.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.
