CVE-2011-4219
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 · uneditedInvestintech.com SlimPDF Reader does not prevent faulting-address data from affecting branch selection, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF document.
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 · moderate confidenceSlimPDF Reader fails to properly sanitize or validate faulting-address data before using it for branch selection logic. This memory corruption vulnerability allows specially crafted PDF documents to either crash the application (DoS) or potentially achieve arbitrary code execution by influencing control flow.

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 if SlimPDF Reader is installedCheck the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'SlimPDF Reader' or check common install directories such as C:\Program Files\SlimPDF Reader or C:\Program Files (x86)\SlimPDF Reader for the executable slimpdf.exeAffected if The application is present on the system
-
Identify the installed versionRight-click slimpdf.exe, select Properties, then view the Details tab to see the File Version, or query the Windows registry uninstall key for the DisplayVersion valueAffected if Any version number is returned, since all versions are affected per the CVE advisory
-
Confirm the product is actively used or handles PDF filesCheck if SlimPDF Reader is set as the default PDF handler or is listed in installed programs associated with PDF file handlingAffected if SlimPDF Reader is configured to open PDF documents, especially those from untrusted or unknown sources
If SlimPDF Reader is installed and configured to handle PDF documents, the environment is affected because all versions of this product contain the vulnerability and specially crafted PDFs can trigger the memory corruption flaw.
Generated from the published advisory. Verify against your own configuration.
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 dataAvoid opening untrusted or unknown PDF documents with SlimPDF Reader. Since this is a 2011 vulnerability in a legacy product, users should migrate to actively-maintained PDF readers that receive current security patches.
