CVE-2011-0334
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 · uneditedStack-based buffer overflow in gwia.exe in GroupWise Internet Agent (GWIA) in Novell GroupWise 8.0 before HP3 allows remote attackers to execute arbitrary code via a long HTTP request for a .css file.
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 confidenceA stack-based buffer overflow vulnerability exists in the GroupWise Internet Agent (gwia.exe) component of Novell GroupWise 8.0 before HP3. The vulnerability is triggered when processing specially crafted HTTP requests for .css files with excessive length, allowing remote attackers to overwrite stack memory and execute arbitrary code.

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.
-
Locate GroupWise Internet Agent executableSearch for gwia.exe on the system or check the GroupWise installation directory (typically in the gwia subfolder of the GroupWise installation path)Affected if gwia.exe is present on the system
-
Identify installed GroupWise versionCheck the GroupWise version by viewing version information of gwia.exe or using the GroupWise administration tools to view the installed versionAffected if The version is GroupWise 8.0 and the Hot Patch (HP) level is below HP3 (e.g., 8.0, 8.0 HP1, 8.0 HP2)
-
Confirm GWIA service is runningCheck if the GroupWise Internet Agent service (GWIA) is running on the server using Windows Services manager or command line: sc query gwiaAffected if The GWIA service is running and exposed to network requests
-
Verify HTTP listener configurationExamine the GWIA configuration to confirm it is configured to accept HTTP connections (check for TCP port 80 or HTTPS port 443 listeners in the GWIA setup)Affected if GWIA is configured to accept HTTP/HTTPS connections from the network
A system is affected if it is running Novell GroupWise 8.0 with a Hot Patch level before HP3 and has the GroupWise Internet Agent service exposed to network requests.

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.
dbcve · scopedUpgrade to Novell GroupWise 8.0 HP3 or later. As an interim measure, restrict network access to the GWIA service using firewalls or network segmentation to limit exposure to untrusted networks.
GroupWise 8.0 HP3 (Hot Patch 3) or later
- Identify the current GroupWise 8.0 Hot Pack (HP) level installed on the GWIA server
- Apply Hot Patch 3 (HP3) or later for GroupWise 8.0 to the affected system
- Verify the patch was applied successfully by checking the GWIA version
- Restart the GWIA service to ensure the patch takes effect
