CVE-2013-1554
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 Network Layer component in Oracle Database Server 10.2.0.4, 10.2.0.5, 11.1.0.7, 11.2.0.2, and 11.2.0.3 allows remote attackers to affect 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.
dbcve analysis · moderate confidenceA vulnerability in the Network Layer of Oracle Database versions 10.2.0.4 through 11.2.0.3 allows remote attackers to impact availability through unspecified vectors. The CVSS 5 score indicates a denial-of-service type issue affecting only availability, with no confidentiality or integrity impact.

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 versionRun the following SQL query against the database: SELECT VERSION FROM V$INSTANCE; or check the oratab file (/etc/oratab or /var/opt/oracle/oratab) on the database server.Affected if The version matches 10.2.0.4, 10.2.0.5, 11.1.0.7, 11.2.0.2, or 11.2.0.3.
-
Verify Oracle Network Listener is runningRun 'lsnrctl status' on the database server or check if process 'tnslsnr' is running (e.g., ps -ef | grep tnslsnr).Affected if The Oracle Network Listener is active and accepting connections.
-
Confirm network exposure of the listenerCheck the LISTENER.ORA file (typically in $ORACLE_HOME/network/admin/) for the ADDRESS configuration, and verify from a remote host that the database port (default 1521) is reachable (e.g., telnet <host> 1521 or nc -zv <host> 1521).Affected if The listener is bound to a publicly accessible IP address or is reachable from untrusted networks.
-
Review listener logging for anomaliesCheck listener log files (located in $ORACLE_HOME/network/log/ or as specified in LISTENER.ORA) for unusual connection patterns or errors around the time of potential exploitation.Affected if Unusual connection attempts or errors are observed that may indicate exploitation attempts.
You are affected if your Oracle Database version is 10.2.0.4, 10.2.0.5, 11.1.0.7, 11.2.0.2, or 11.2.0.3 AND the Oracle Network Listener is running and accessible from the network.

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.
From vendor dataApply Oracle Critical Patch Update April 2013 (or subsequent patches addressing CVE-2013-1554) to all affected database instances. If immediate patching is not feasible, implement network-level filtering to restrict untrusted access to database network listeners.
