CVE-2008-1925
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 · uneditedBuffer overflow in InspIRCd before 1.1.18, when using the namesx and uhnames modules, allows remote attackers to cause a denial of service (daemon crash) via a large number of channel users with crafted nicknames, idents, and long hostnames.
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 in InspIRCd versions prior to 1.1.18 when the namesx and uhnames modules are enabled. The vulnerability allows remote attackers to crash the IRC daemon by sending a large number of channel users with crafted nicknames, idents, and excessively long hostnames that exceed buffer boundaries.

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 InspIRCd installationRun `which inspircd` or look for the inspircd binary in common paths like /usr/bin/inspircd or /usr/local/bin/inspircdAffected if InspIRCd is present on the system
-
Determine installed InspIRCd versionRun `inspircd --version` or check the binary version with `inspircd -v`. If the binary is not directly executable, check the package version using your OS package manager (dpkg -l inspircd or rpm -q inspircd)Affected if The version is 1.1.17 or lower
-
Locate InspIRCd configuration directoryCheck common config paths: /etc/inspircd/, /etc/inspircd/conf/, or the directory specified at startup (inspircd --config /path/to/inspircd.conf)Affected if A configuration file (inspircd.conf) exists
-
Check if namesx module is loadedSearch the InspIRCd configuration file for <module name="namesx"> or a LoadModule directive referencing namesx, or run 'inspircd --modules' if available to list loaded modulesAffected if The namesx module is enabled in the configuration
-
Check if uhnames module is loadedSearch the InspIRCd configuration file for <module name="uhnames"> or a LoadModule directive referencing uhnames, or check the module list as described aboveAffected if The uhnames module is enabled in the configuration
Your system is affected if InspIRCd version is 1.1.17 or lower AND at least one of the namesx or uhnames modules is enabled in the configuration

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 InspIRCd to version 1.1.18 or later, or temporarily disable the namesx and uhnames modules as a workaround until the upgrade can be completed.
