CVE-2008-2090
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 SCTP protocol implementation in Sun Solaris 10 allows remote attackers to cause a denial of service (CPU consumption and network traffic amplification) via a crafted SCTP packet.
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 confidenceThis is a denial-of-service vulnerability in Sun Solaris 10's SCTP (Stream Control Transmission Protocol) implementation. Remote attackers can send specially crafted SCTP packets that cause excessive CPU consumption and generate network traffic amplification, leading to service degradation or complete unavailability.

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.
-
Verify the operating system is Sun Solaris 10Run 'uname -r' or 'cat /etc/release' to confirm the installed OS version is Solaris 10Affected if The OS version is Sun Solaris 10 (version = 10)
-
Check if SCTP kernel module is loadedRun 'modinfo | grep sctp' or 'lsmod | grep sctp' to see if the SCTP module is currently loaded in the kernelAffected if The SCTP kernel module (sctp) is loaded and active
-
Verify SCTP is enabled in the systemCheck the SCTP service status with 'svcs -a | grep sctp' or look for SCTP-related entries in /etc/services to confirm SCTP services are configuredAffected if SCTP protocol is enabled and SCTP services exist on the system
-
Check for active SCTP listeners or bindingsUse 'netstat -anp | grep sctp' or 'sctp_advertise' (if available) to list any SCTP endpoints currently listening for connectionsAffected if There are SCTP listeners or established SCTP connections accepting traffic
A system is affected if it is running Sun Solaris 10 with the SCTP protocol stack enabled and actively processing SCTP traffic.

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 the relevant Sun/Oracle patch for this vulnerability. If SCTP is not required in the environment, consider disabling the SCTP protocol stack or filtering SCTP traffic at network boundaries to reduce attack surface.
