CVE-2008-0768
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 · uneditedMultiple stack-based and heap-based buffer overflows in the Windows RPC components for IBM Informix Storage Manager (ISM), as used in Informix Dynamic Server (IDS) 10.00.xC8 and earlier and 11.10.xC2 and earlier, allow attackers to execute arbitrary code via crafted XDR requests.
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 · high confidenceBuffer overflow vulnerability in IBM Informix Storage Manager's Windows RPC components allows remote attackers to execute arbitrary code via crafted XDR (External Data Representation) requests. Both stack-based and heap-based overflows are present in the affected versions.

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.
-
Check for IBM Informix Dynamic Server installation and versionOn Windows, check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Informix\Version or inspect the installation directory (typically C:\IBM\Informix) for version information. Use 'onstat -' command if the Informix environment is accessible.Affected if The installed version falls within 10.0 to 10.00.xc8 OR 11.10 to 11.10.xc2 on a Windows system.
-
Check for IBM Informix Storage Manager installationLook for the Informix Storage Manager (ism) component in the Windows installation. Common locations include C:\IBM\Informix\StorageManager or search for ISM-related executables and services.Affected if IBM Informix Storage Manager is present on the system, regardless of version.
-
Identify if the Informix RPC service is runningOn Windows, open Services (services.msc) and look for Informix-related RPC services, or use the command 'sc query' to enumerate services containing 'Informix' in the name. Check if the Windows RPC Server (RpcSs) service and Informix RPC listener ports are active.Affected if Informix RPC services are enabled and listening on network ports.
-
Confirm the operating system is WindowsVerify the host operating system is Windows, as this vulnerability specifically affects Windows RPC components as noted in the CVE description.Affected if The affected system is running Windows with IBM Informix products installed.
A system is affected if it runs IBM Informix Dynamic Server (versions 10.0 through 10.00.xc8 or 11.10 through 11.10.xc2) or any version of IBM Informix Storage Manager on Windows, with the RPC service component enabled and exposed.

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 dataUpgrade IBM Informix Dynamic Server to a version beyond 10.00.xC8 and 11.10.xC2, or apply available vendor patches. If immediate patching is not feasible, restrict network access to RPC services listening on affected ports.
