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
Unspecified vulnerability in the Java 2D component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, 1.4.2_25, and 1.3.1_27 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is a heap-based buffer overflow that allows arbitrary code execution via a crafted image.

dbcve analysis · high confidence

CVE-2010-0847 is a heap-based buffer overflow vulnerability in the Java 2D component that allows remote attackers to execute arbitrary code via a crafted image file. This flaw affects multiple legacy Java versions (1.3.1_27, 1.4.2_25, 5.0_23, 6 Update 18) and enables complete compromise of affected systems through the high-severity CVSS rating of 7.5.

MitigationApply the relevant Java Critical Patch Update (CPU) from March 2010 that addresses this vulnerability, or upgrade to a patched Java version beyond the affected releases. If immediate patching is not feasible, disable Java browser plugins and restrict Java applet execution until updates can be deployed.

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 runtime version
    Run 'java -version' or 'java -fullversion' from command line to obtain the JRE/JDK version string
    Affected if The version matches or is older than: 1.6.0 (any update), 1.5.0 (any update), 1.4.2_25 or lower, or any of the specific 1.4.2_x versions listed (1, 2, 3, 4, 5, 6)
  2. Confirm Java 2D component is present
    Verify the JRE/JDK includes the Java 2D library by checking for the presence of the rt.jar or j2d.jar in the JRE lib directory (for example, $JAVA_HOME/jre/lib/rt.jar)
    Affected if The Java 2D library files exist in the installed Java runtime
  3. Determine if Java applets or Java Web Start are enabled
    Check browser plugin configuration (for Internet Explorer, look in Manage Add-ons; for Firefox, check Plugins under Add-ons) and look for 'Java Plug-in' or 'Java Deployment Toolkit' entries
    Affected if Java browser plugins are enabled or Java Web Start is installed and accessible
  4. Identify Java processes handling untrusted image files
    Review running Java applications or services that process image input from untrusted sources, such as image converters, document processors, or media handlers that use Java
    Affected if Java applications process image files from untrusted or external sources without additional validation

A system is affected if it runs any Java version matching the affected ranges (1.6.0 and below, 1.5.0 and below, 1.4.2_25 and below, or specific 1.4.2_x/1.3.x variants) AND has Java 2D accessible through applets, Java Web Start, or applications that process untrusted image files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 1.6.0
Interim mitigation

Apply the relevant Java Critical Patch Update (CPU) from March 2010 that addresses this vulnerability, or upgrade to a patched Java version beyond the affected releases. If immediate patching is not feasible, disable Java browser plugins and restrict Java applet execution until updates can be deployed.
