CVE-2011-2144
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 · uneditedThe eDocument Conversion Actions implementation in IBM Datacap Taskmaster Capture 8.0.1 FP1 and earlier allows remote attackers to cause a denial of service (batch abort) via a long subject line in an e-mail message that is represented in a .eml 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 · high confidenceThe eDocument Conversion Actions in IBM Datacap Taskmaster Capture 8.0.1 FP1 and earlier fails to properly validate or handle excessively long subject lines in .eml (e-mail) files, causing the application to abort processing batches when encountering this input condition.

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.
-
Verify IBM Datacap Taskmaster Capture versionLocate the installed Taskmaster Capture application and check its version number in the program files, application properties, or installer information. Compare this version to the affected range: versions 8.0.1 and earlier.Affected if The installed version is 8.0.1 or any version lower than 8.0.1 (8.0.1, 8.0.0, 7.x, etc.)
-
Confirm eDocument Conversion Actions is enabledAccess the Taskmaster Capture configuration or workflow settings and verify whether the eDocument Conversion Actions component is actively enabled for the current task or profile.Affected if eDocument Conversion Actions is enabled and configured for use in batch processing workflows
-
Verify .eml file processing is configuredCheck the task or batch profile settings to determine if the application is set up to process .eml (email) files through the eDocument Conversion Actions.Affected if The system is configured to accept and process .eml files as input for batch processing
-
Review batch processing logs for failuresExamine the Taskmaster Capture application logs, event logs, or batch output files for any instances where batch processing aborted or failed specifically when encountering .eml files with long subject lines.Affected if Batch processing has aborted or produced errors when processing .eml files, particularly if the failure mentions email subject lines or message headers
You are affected if you are running version 8.0.1 or earlier, have eDocument Conversion Actions enabled, process .eml files, and have experienced batch processing failures with email files.

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 dataApply any available vendor patches for this version. If no patch exists, implement input validation logic in the eDocument Conversion Actions component to truncate or reject subject lines exceeding reasonable length thresholds before batch processing.
