Unspecified vulnerability in IBM Java Runtime Environment (JRE) 7 R1 before SR2 (7.1.2.0), 7 before SR8 (7.0.8.0), 6 R1 before SR8 FP2 (6.1.8.2), 6 before SR16 FP2 (6.0.16.2), and before SR16 FP8 (5.0.16.8) allows local users to execute arbitrary code via vectors related to the shared classes cache.

Technical summary

dbcve analysis · high confidence

IBM Java Runtime Environment versions prior to the specified SR/FP updates contain an unspecified vulnerability in the shared classes cache functionality that allows local users to execute arbitrary code. The attack vector is local (AV:L), requiring the attacker to have some level of access to the affected system.

MitigationUpgrade IBM JRE to version 7 R1 SR2 (7.1.2.0) or later, 7 SR8 (7.0.8.0) or later, 6 R1 SR8 FP2 (6.1.8.2) or later, 6 SR16 FP2 (6.0.16.2) or later, or 5 SR16 FP8 (5.0.16.8) or later.

Am I affected?

dbcve checks

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

Identify IBM Java installation

Run 'java -version' or check for IBM JRE/JDK binaries in common locations such as /opt/ibm/java, /usr/lib/jvm/ibm*, or Windows equivalents under C:\Program Files\IBM\Java. Look for IBM-specific banner output.

Affected if IBM Java is installed and the output shows an IBM-specific version string rather than Oracle/OpenJDK.
Determine exact IBM Java version

Execute 'java -version 2>&1' and capture the full version string. For IBM Java 5, look for versions in the 5.0.x series such as 5.0.0.0 through 5.0.14.0, including SR and FP designations like SR16 FP8.

Affected if The installed version matches any of: 5.0.0.0, 5.0.11.0, 5.0.11.1, 5.0.11.2, 5.0.12.0, 5.0.12.1, 5.0.12.2, 5.0.12.3, 5.0.12.4, 5.0.12.5, 5.0.13.0, or 5.0.14.0.
Verify shared classes cache is in use

Search for shared class cache files in the system. On Unix/Linux check for .idx files in /tmp or the java.io.tmpdir, or run 'java -XshowSettings:all 2>&1 | grep -i share' to display shared class cache settings. On Windows check user temp directories for .idx files created by IBM Java.

Affected if Shared classes cache is enabled and .idx cache files exist, as this is the vulnerable component. The vulnerability requires the shared classes cache functionality to be active.

You are affected if IBM Java 5.0.x versions up to 5.0.14.0 are installed AND the shared classes cache feature is in use on the local system.

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

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.
