Unspecified vulnerability in Oracle Java SE 6u75, 7u60, and 8u5 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.

Technical summary

dbcve analysis · moderate confidence

Oracle Java SE vulnerability in the Hotspot component affecting versions 6u75, 7u60, and 8u5. The specific vulnerability details are unspecified with unknown attack vectors, but the CVSS 9.3 indicates complete impact on confidentiality, integrity, and availability.

MitigationUpgrade to a later supported Oracle Java SE version beyond 8u5 that includes the security fix, or apply Oracle's corresponding CPU patch if available for the affected versions.

Am I affected?

dbcve checks

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

Check if Java is installed

Run 'java -version' or 'which java' to determine if Java is present on the system

Affected if Java is not installed or not found, then the system is not affected by this specific Java vulnerability
Identify the installed Java version

Run 'java -version' and note the full version string (for example: 1.6.0_75, 1.7.0_60, 1.8.0_5)

Affected if The version falls within 1.6.0 through 1.6.0_75, 1.7.0 through 1.7.0_60, or 1.8.0 through 1.8.0_5, indicating the system may be affected
Confirm the JVM implementation is Oracle Hotspot

Run 'java -version -verbose' or check the JRE/lib directory for hotspot folders. Oracle Java SE typically uses the Hotspot JVM by default

Affected if The JVM is Oracle Hotspot and the version falls within the affected range, then the vulnerability applies
Check if the Java browser plugin is enabled

Verify browser plugin settings in Java Control Panel (Java Plug-in) or examine browser configuration for Java applet support

Affected if Browser plugin is enabled and Java version is in the affected range, the attack surface for this vulnerability is present

If Oracle Java (JDK or JRE) version 1.6.0 through 1.6.0_75, 1.7.0 through 1.7.0_60, or 1.8.0 through 1.8.0_5 using the Hotspot JVM is installed, the environment is affected by CVE-2014-4219

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

Remediation

dbcve · scoped

Mitigation available No clean upgrade yet — mitigate in the meantime

Mitigation

Upgrade to a later supported Oracle Java SE version beyond 8u5 that includes the security fix, or apply Oracle's corresponding CPU patch if available for the affected versions.

Recommended fix Moderate confidence

Java SE 6u81+ / Java SE 7u65+ / Java SE 8u11+ (Oracle Critical Patch Updates)

1. Identify the currently installed Java version using 'java -version' command
2. Download the appropriate Oracle Critical Patch Update (CPU) for your Java version from oracle.com/technetwork/java/javase/downloads/
3. For Java 1.6.0 (Java 6), upgrade to Java SE 6u81 or later
4. For Java 1.7.0 (Java 7), upgrade to Java SE 7u65 or later
5. For Java 1.8.0 (Java 8), upgrade to Java SE 8u11 or later
6. Uninstall the vulnerable Java version or ensure the new version is the default
7. Verify the fix by running 'java -version' and confirming the updated version number

Caveat CPU updates are patch-level and typically backward-compatible; however, test in non-production first

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.

Check your environment

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.
