CVE-2009-0176
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 · uneditedMultiple heap-based buffer overflows in the PDF distiller in the Attachment Service in Research in Motion (RIM) BlackBerry Enterprise Server (BES) 4.1.3 through 4.1.6, BlackBerry Professional Software 4.1.4, and BlackBerry Unite! before 1.0.3 bundle 28 allow user-assisted remote attackers to execute arbitrary code via (1) a crafted stream in a .pdf file, related to "symWidths"; or (2) a crafted data stream in a .pdf file, related to "bitmaps."
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 confidenceHeap-based buffer overflow vulnerabilities in the PDF distiller component of BlackBerry Enterprise Server's Attachment Service allow remote attackers to execute arbitrary code via specially crafted PDF files containing malformed streams (symWidths) or bitmap data. The vulnerability is user-assisted, requiring a user to open or process a malicious PDF attachment.

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 installed BlackBerry server productLocate the installed BlackBerry Enterprise Server, BlackBerry Professional Software, or BlackBerry Unite installation directory and determine which product is present. Check common installation paths or use system inventory tools.Affected if The product is BES 4.1.3-4.1.6, BlackBerry Professional Software 4.1.4, or BlackBerry Unite version 1.0 through 1.0.3 (including versions <=1.0.3).
-
Determine the installed versionCheck the product version by examining the installed software properties, About screen, or version information file within the BlackBerry installation directory.Affected if The version matches 4.1.3, 4.1.4, 4.1.5, or 4.1.6 for BES; 4.1.4 for BlackBerry Professional Software; or 1.0, 1.0.1, 1.0.2, or 1.0.3 for BlackBerry Unite.
-
Verify Attachment Service is enabledCheck the BlackBerry Attachment Service configuration or service status. This service handles processing of attachments including PDFs.Affected if The Attachment Service is running and processing attachments.
-
Confirm PDF attachment processing is activeReview the Attachment Service settings to determine if PDF file processing is enabled or allowed for incoming attachments.Affected if PDF file types are set to be processed by the Attachment Service.
The environment is affected if a vulnerable BlackBerry product version (BES 4.1.3-4.1.6, Professional Software 4.1.4, or Unite 1.0-1.0.3) is installed with the Attachment Service running and PDF processing enabled, allowing users to open malicious PDF attachments.

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 vendor patches for affected BlackBerry products (BES 4.1.3-4.1.6, BlackBerry Professional Software 4.1.4, and Unite! before 1.0.3 bundle 28). Consider disabling PDF attachment processing in the Attachment Service as a temporary workaround until patching is complete.
