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 Oracle Java SE 7u51 and 8, and Java SE Embedded 7u51, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.

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 · high confidence

CVE-2014-2397 is an unspecified vulnerability in Oracle Java's Hotspot component (the JIT compiler). The high CVSS score (9.3) indicates a remote, network-exploitable flaw requiring no authentication and providing complete compromise of confidentiality, integrity, and availability through unknown vectors in the Java runtime's JIT compilation process.

MitigationApply the relevant Oracle Critical Patch Update (CPU) that addresses CVE-2014-2397, which includes updating Oracle Java SE to a patched version (beyond 7u51/8) across all affected systems.

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. Check if Java is installed
    Run 'which java' on Linux/Unix or check Program Files\Java on Windows. Also try 'java -version' command.
    Affected if No Java runtime is found - not affected. If Java exists, continue to next step.
  2. Identify the Java vendor and version
    Run 'java -version' and examine the output. Look for vendor name (must be Oracle or Sun) and version string (e.g., 1.7.0_45, 1.8.0_5).
    Affected if If vendor is Oracle/Sun and version starts with 1.7.0 or 1.8.0, continue to next step. Other vendors (OpenJDK, IBM, etc.) may have separate patches.
  3. Confirm the Hotspot JIT compiler is in use
    Run 'java -version -verbose' or check the JVM info. Oracle Java with version 1.7.x or 1.8.x uses the Hotspot JIT compiler by default.
    Affected if If running Oracle Java 1.7.x or 1.8.x, the Hotspot component is present and potentially vulnerable.
  4. Compare installed version against patched releases
    The vulnerability was fixed in Java 7u51 (1.7.0_51) and Java 8u20 (1.8.0_20). Compare your installed version number against these milestones.
    Affected if If the installed version is earlier than 7u51 or 8u20, the system is vulnerable to CVE-2014-2397.

A system is affected if it runs any Oracle JDK or JRE version 1.7.0 through 1.7.0_50, or 1.8.0 through 1.8.0_19, because these versions contain the vulnerable Hotspot JIT compiler component.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the relevant Oracle Critical Patch Update (CPU) that addresses CVE-2014-2397, which includes updating Oracle Java SE to a patched version (beyond 7u51/8) across all affected systems.

Recommended fix High confidence

Java SE 7u60+ or Java SE 8u40+ (or latest available patched release)

  1. 1. Identify the currently installed Java version by running 'java -version' or 'javac -version'
  2. 2. For Oracle Java SE: Download and install Java SE 7u60 or later, or Java SE 8u40 or later from the Oracle Java SE download page
  3. 3. For OpenJDK (Debian/Ubuntu): Run 'sudo apt-get update' followed by 'sudo apt-get upgrade openjdk-7-jdk' or 'sudo apt-get upgrade openjdk-8-jdk' to install the latest security patches
  4. 4. Verify the new Java version is active by running 'java -version'
  5. 5. Ensure the JAVA_HOME environment variable points to the updated Java installation if needed
Caveat Upgrading Java may require recompiling applications if they depend on specific JVM behavior; test thoroughly in a non-production environment first
