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 · unedited
Buffer overflow in gwwww1.dll in GroupWise Internet Agent (GWIA) in Novell GroupWise before 8.02HP2 allows remote attackers to execute arbitrary code via a crafted TZID variable in a VCALENDAR message.

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 confidence

A buffer overflow vulnerability exists in gwwww1.dll within the GroupWise Internet Agent (GWIA) component. The flaw is triggered when parsing a specially crafted TZID (Time Zone Identifier) variable within a VCALENDAR (iCalendar) message. Successful exploitation allows remote attackers to execute arbitrary code by overwriting stack memory through the malformed TZID value.

MitigationApply Novell GroupWise 8.02HP2 or later patch which addresses the buffer overflow in the VCALENDAR TZID parsing routine within the GWIA component.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm GWIA is installed and running
    On Windows, check services.msc for 'GroupWise Internet Agent' service or look for gwia.exe in the GroupWise installation directory. On Linux, check for gwia processes.
    Affected if GWIA service or process is not present on the system, then the vulnerability does not apply.
  2. Identify installed GroupWise version
    Check the GroupWise version by looking at the GWIA binary properties (right-click gwwww1.dll and view Version tab) or check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Novell\GroupWise\InstallDir or the version file in the GroupWise directory.
    Affected if The installed version matches one of these: 4.1, 4.1a, 5.0, 5.1, 5.2, 5.5, 5.57e, 6.0, 6.0.1, 6.5, 6.5.2, or any version 8.0.2 or lower.
  3. Locate and verify gwwww1.dll version
    Find gwwww1.dll in the GWIA installation directory (typically in the gwia subfolder of the GroupWise installation). Right-click the file, select Properties, and note the File Version.
    Affected if The DLL version corresponds to an affected GroupWise version from step 2.
  4. Verify GWIA is configured to accept external VCALENDAR data
    Check GWIA configuration settings to confirm it is accepting SMTP connections or processing iCalendar/VCALENDAR attachments from external sources. Look at the GWIA console or configuration files for enabled handlers.
    Affected if GWIA is configured to receive and process VCALENDAR data from untrusted sources, exposing the parsing vulnerability.

You are affected if GWIA is running with a GroupWise version of 8.0.2 or lower (including 4.1 through 6.5.2) and GWIA is configured to process incoming VCALENDAR data from external sources.

Upgrade available Upgrade to a release after 8.0.2
Interim mitigation

Apply Novell GroupWise 8.02HP2 or later patch which addresses the buffer overflow in the VCALENDAR TZID parsing routine within the GWIA component.

Recommended fix Moderate confidence

GroupWise 8.02HP2 (or later supported release)

  1. 1. Identify the current GroupWise Internet Agent (GWIA) version in use
  2. 2. Obtain the GroupWise 8.02HP2 or later update from Novell's support portal or authorized distribution channels
  3. 3. Schedule a maintenance window for the upgrade
  4. 4. Backup the current GroupWise configuration and data
  5. 5. Apply the GroupWise 8.02HP2 update to the GWIA component
  6. 6. Verify the gwwww1.dll version matches the patched release
  7. 7. Test VCALENDAR message processing to confirm the TZID variable handling is fixed
  8. 8. Monitor logs for any residual issues
Caveat Upgrading major versions (e.g., from 4.x/5.x to 8.x) may require migration procedures and compatibility checks with dependent systems
