CVE-2014-4236
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 · uneditedUnspecified vulnerability in the RDBMS Core component in Oracle Database Server 11.2.0.4 and 12.1.0.1 allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors.
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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Oracle Database Server installationQuery the database by connecting via SQL*Plus or other client and run: SELECT * FROM v$version WHERE banner LIKE 'Oracle Database%';Affected if Oracle Database Server is not installed - you are not affected by this CVE
-
Determine exact database versionRun: SELECT version FROM product_component_version WHERE product LIKE 'Oracle Database%'; or check the output from v$version for the exact version number (e.g., 11.2.0.4.0 or 12.1.0.1.0)Affected if The exact version is 11.2.0.4 or 12.1.0.1 - you are potentially affected by this CVE
-
Verify if remote authenticated access is possibleConfirm that the database listener (TNS) is configured to accept remote connections and that valid authentication credentials exist. Check listener.ora for LISTENER configuration and verify network access to port 1521 (default).Affected if Remote authenticated access to the database is enabled and credentials are available - exploitation becomes possible if you are on an affected version
You are affected only if your Oracle Database Server is exactly version 11.2.0.4 or 12.1.0.1 AND remote authenticated access to the database is possible.
