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
Multiple buffer overflows in the PDF Distiller in the BlackBerry Attachment Service component in Research In Motion (RIM) BlackBerry Enterprise Server 4.1.3 through 5.0.2, and Enterprise Server Express 5.0.1 and 5.0.2, allow remote attackers to execute arbitrary code via a crafted PDF 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 confidence

Multiple buffer overflows in the PDF Distiller component of the BlackBerry Attachment Service allow remote attackers to execute arbitrary code by sending specially crafted PDF files through the attachment processing pipeline.

MitigationUpgrade BlackBerry Enterprise Server to a version beyond 5.0.2 that includes the patch, or disable the Attachment Service if not required; implement email gateway filtering to block untrusted PDF attachments as a compensating control.

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. Identify installed BlackBerry Enterprise Server version
    Check the version through the BlackBerry Administration Service, or run the BBES Version checker utility from the installation directory, or inspect the registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server on the server
    Affected if The installed version is any of the following: 4.1.3, 4.1.4, 4.1.5, 4.1.6, 4.1.7, 5.0.0, 5.0.1, or 5.0.2 (for BES), or 5.0.1 or 5.0.2 (for BES Express)
  2. Verify Attachment Service is enabled
    Open the BlackBerry Administration Service, navigate to Server Configuration, and confirm the Attachment Service status, or check the BAS logs for Attachment Service initialization
    Affected if The Attachment Service is running or enabled on the server
  3. Confirm PDF Distiller component is active
    Inspect the Attachment Service configuration in the BlackBerry Administration Service to verify the PDF Distiller module is loaded, or review the Attachment Service log files for PDF processing activity
    Affected if PDF Distiller is listed as an active handler for PDF attachments in the Attachment Service pipeline
  4. Check for inbound PDF attachment processing
    Review Attachment Service logs for incoming PDF files being processed through the distiller component, or monitor network traffic on the Attachment Service port for PDF attachment transfers
    Affected if The server processes PDF attachments through the Attachment Service pipeline

You are affected if your BlackBerry Enterprise Server version is 4.1.3-5.0.2 (or 5.0.1-5.0.2 for Express) AND the Attachment Service with PDF Distiller is enabled and actively processing PDF attachments.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade BlackBerry Enterprise Server to a version beyond 5.0.2 that includes the patch, or disable the Attachment Service if not required; implement email gateway filtering to block untrusted PDF attachments as a compensating control.

Recommended fix Moderate confidence

BlackBerry Enterprise Server 5.0.3 or later (contact RIM for exact patched version)

  1. Contact RIM (BlackBerry) directly or visit their official support portal to obtain the specific security update for this CVE
  2. Request KB33785 or the relevant security bulletin for CVE-2010-2604 which contains the patched version
  3. Apply the update through your BlackBerry Enterprise Server administration console following RIM's documented procedures
Caveat Test the upgrade in a non-production environment before deploying; review RIM's release notes for any configuration or compatibility changes
