CVE-2008-2089
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 (panic) 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 a specially crafted SCTP packet that triggers a kernel panic, causing the system to crash. The vulnerability is in the protocol stack and does not require 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 Sun Solaris 10 is runningRun 'uname -a' or 'cat /etc/release' to identify the operating system and version. Look for 'Solaris 10' in the output.Affected if The system is running Solaris 10 (any update level)
-
Verify SCTP is enabled or loadedCheck if the SCTP kernel module is loaded or if SCTP is configured. Run 'modinfo | grep sctp' to list SCTP-related kernel modules, or check for SCTP in /etc/system or via 'ipf -p' output for SCTP protocol handling.Affected if SCTP kernel modules are loaded or SCTP protocol handling is enabled in the system
-
Check if SCTP services are listeningRun 'netstat -an' or 'snoop -sctp' (if available) to see if any SCTP ports are listening or if SCTP traffic is being processed. Also check 'svcs -a | grep sctp' for SCTP-related services.Affected if Any SCTP listener is active or SCTP traffic is being processed by the kernel
-
Review SCTP configurationInspect the system's network configuration for SCTP settings. Check /etc/inet/ipnodes or run 'showrev -p' to see installed patches, though specific patch numbers are not provided here.Affected if SCTP is configured in the network stack regardless of active connections
The environment is affected if it runs Sun Solaris 10 and has SCTP protocol support enabled or loaded in the kernel, as the vulnerability triggers via crafted SCTP packets processed by the kernel.

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 appropriate Sun patch for this vulnerability (contact Oracle for legacy Solaris support). If SCTP is not required, consider disabling it. Network filtering of unexpected SCTP traffic at the perimeter may provide partial workarounds.
