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 5.0u65, 6u75, 7u60, and 8u5 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Libraries.

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

This is an unspecified vulnerability in the Libraries component of Oracle Java SE versions 5.0u65, 6u75, 7u60, and 8u5. The vulnerability is remotely exploitable and allows attackers to impact confidentiality, integrity, and availability, though the specific attack vectors and technical details are not publicly disclosed.

MitigationApply the appropriate Java SE security updates for versions 5.0u65, 6u75, 7u60, and 8u5, or upgrade to later supported Java versions to remediate this vulnerability.

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 JRE/JDK version
    Run 'java -version' from command line and note the full version string (e.g., 1.8.0_5). On Windows, also check registry under HKLM\SOFTWARE\JavaSoft\Java Runtime Environment for the CurrentVersion and associated JavaHome values.
    Affected if The reported version matches 1.5.0u65, 1.6.0u75, 1.7.0u60, or 1.8.0u5 exactly, or falls within the 1.5.0, 1.6.0, 1.7.0, or 1.8.0 family branches at those update levels.
  2. Locate all Java installations on the system
    Search for java.exe (Windows) or java binary (Unix/Linux) in common installation paths: C:\Program Files\Java\, /usr/lib/jvm/, /usr/java/, or use 'which java' and 'find /usr -name java -type f' on Unix systems.
    Affected if Any discovered Java installation reports a version in the affected ranges listed above.
  3. Check for Java Web Start installations
    On Windows, look for javaws.exe in Program Files\Java\ or check the Add/Remove Programs list for Java Web Start entries. On Linux, check /usr/bin/javaws or ~/.local/share/javaws/.
    Affected if Java Web Start is present and runs an affected Java version, since the Libraries component vulnerability can be triggered through JNLP applications.
  4. Determine Java usage context
    Identify if Java is used server-side (application servers, web services) or client-side (browser plugins, desktop applications). Check for running Java processes using 'tasklist' on Windows or 'ps aux | grep java' on Unix.
    Affected if Java is running and accessible to untrusted network sources, as the vulnerability is remotely exploitable through the Libraries component.

If any installed Java version is exactly 1.5.0u65, 1.6.0u75, 1.7.0u60, or 1.8.0u5 (or falls within those family branches), and that Java is exposed to network or untrusted code execution paths, the environment is likely affected by CVE-2014-4262.

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

Apply the appropriate Java SE security updates for versions 5.0u65, 6u75, 7u60, and 8u5, or upgrade to later supported Java versions to remediate this vulnerability.

Recommended fix Moderate confidence

Oracle Java SE 5.0 Update 66+, 6.0 Update 76+, 7.0 Update 65+, or 8.0 Update 11+ (whichever is the next CPU release for your major version line)

  1. 1. Identify all systems running affected Java versions (JDK/JRE 1.5.0, 1.6.0, 1.7.0, 1.8.0)
  2. 2. Determine the specific Java version installed on each system using 'java -version' or checking the JRE/JDK directory
  3. 3. For Java 1.5.0 (5.0): Upgrade to version 1.5.0_66 or later from Oracle's Java SE downloads
  4. 4. For Java 1.6.0 (6.0): Upgrade to version 1.6.0_76 or later from Oracle's Java SE downloads
  5. 5. For Java 1.7.0 (7u60): Upgrade to version 1.7.0_65 or later (the next Critical Patch Update after 7u60)
  6. 6. For Java 1.8.0 (8u5): Upgrade to version 1.8.0_11 or later (the next CPU release after 8u5)
  7. 7. Download the updated Java packages from Oracle's official Java SE download page
  8. 8. Install the updated Java version following standard installation procedures
Caveat Java 5 and 6 are End-of-Life and no longer receive public updates; consider upgrading to Java 8 LTS or later for continued support
