CVE-2013-3753
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 Oracle Solaris 11 allows remote attackers to affect availability via vectors related to Kernel/STREAMS framework.
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 confidenceUnspecified vulnerability in Oracle Solaris 11's Kernel/STREAMS framework allows remote attackers to impact system availability, likely causing a denial of service condition. The vulnerability resides in kernel-level network streaming components and is exploitable remotely without authentication.

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.
-
Confirm Oracle Solaris 11 versionRun 'uname -a' or 'cat /etc/release' to identify the exact Solaris versionAffected if The version displayed is Solaris 11 (Sunos 5.11)
-
Identify running STREAMS modulesRun 'modinfo | grep -i stream' to list loaded STREAMS-related kernel modulesAffected if STREAMS modules such as 'str' or 'stream' are listed as loaded
-
Check for active network listeners using STREAMSRun 'netstat -an | grep LISTEN' to identify listening network servicesAffected if Network services are bound to listening ports, especially on production network interfaces
-
Verify kernel STREAMS configurationCheck '/etc/system' or run 'ndd' commands for STREAMS parameters (e.g., 'ndd /dev/tcp tcp_str_elem')Affected if STREAMS kernel parameters exist and are accessible
-
Assess network exposureReview firewall rules and network configuration using 'ipf -V' or 'pfctl -sr' to determine if the system accepts remote network trafficAffected if The system has open network access from untrusted networks without strict filtering
A system is affected if it runs Oracle Solaris 11 (Sunos 5.11) with STREAMS kernel modules loaded and exposed to network traffic, allowing remote unauthenticated attackers to trigger the denial of service condition.

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 Updates for Solaris 11 to address the kernel/STREAMS vulnerability. As a compensating control, restrict network access to affected Solaris systems to limit remote attack surface until patching can be scheduled.
