CVE-2010-4711
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 · uneditedDouble free vulnerability in the IMAP server component in GroupWise Internet Agent (GWIA) in Novell GroupWise before 8.02HP allows remote attackers to execute arbitrary code via a large parameter in a LIST command.
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 confidenceA double-free memory corruption vulnerability exists in the IMAP server component (GroupWise Internet Agent) of Novell GroupWise versions prior to 8.02HP. The flaw is triggered by sending a specially crafted LIST command containing an oversized parameter, which can be exploited by remote attackers to execute arbitrary code with the privileges of the GWIA service.

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 GroupWise versionLocate the GroupWise installation directory and check the version information, typically found in a version file, About dialog, or system information panel within the GroupWise admin toolsAffected if The installed version matches any of the following: 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 earlier (including 8.0, 8.0.1, 8.0.2)
-
Confirm IMAP component is presentVerify that the GroupWise Internet Agent (GWIA) component is installed on the system. This can be checked through the GroupWise administration console, Windows Services snap-in, or by searching for GWIA-related processes or servicesAffected if The GWIA service or process is present on the system
-
Check if IMAP service is enabled and runningExamine whether the IMAP service (typically listening on port 143) is in a listening state. Use netstat, ss, or the operating system's service management tool to verify the service is activeAffected if The IMAP service is running and bound to a network interface
-
Verify network exposure of IMAP portDetermine if the IMAP port (default 143) is exposed to untrusted networks. Review firewall rules, network configuration, or use port scanning tools to identify listening services accessible from outside the trusted networkAffected if Port 143 is accessible from networks outside the trusted/internal network
You are affected if your environment runs a vulnerable GroupWise version (8.0.2 or earlier, or any of the specific versions listed) with the GWIA IMAP component enabled and the service is network-accessible.

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 Novell GroupWise to version 8.02HP or later to remediate this vulnerability. If immediate patching is not feasible, restrict network access to the IMAP service (typically port 143) using firewall rules or ACLs to limit exposure to untrusted networks.
8.02HP or later
- Back up the existing GroupWise installation and all associated databases
- Download Novell GroupWise 8.02HP or later from the Novell support portal
- Stop all GroupWise services including the GroupWise Internet Agent (GWIA)
- Install the GroupWise 8.02HP update following Novell's official upgrade documentation
- Restart GroupWise services and verify the GWIA component is running
- Confirm the IMAP service is functioning correctly with the LIST command
