CVE-2017-2822
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 · uneditedAn exploitable code execution vulnerability exists in the image rendering functionality of Lexmark Perceptive Document Filters 11.3.0.2400. A specifically crafted PDF can cause a function call on a corrupted DCTStream to occur, resulting in user controlled data being written to the stack. A maliciously crafted PDF file can be used to trigger this vulnerability.
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 stack-based buffer overflow vulnerability exists in Lexmark Perceptive Document Filters 11.3.0.2400 where a specially crafted PDF file triggers a function call on a corrupted DCTStream (JPEG image data stream) during image rendering. This allows attacker-controlled data to be written to the stack, leading to potential remote code execution.

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 Lexmark Perceptive Document Filters installationCheck for the product in installed programs (Windows Add/Remove Programs, or Linux package manager), or look for the application executable in its default installation directoryAffected if The product is installed on the system
-
Determine the installed versionRight-click the executable file (typically named PDFIF.exe or similar in the installation folder) and select Properties, then check the Version tab. Alternatively, open the application and look in Help > About or use the command line: pdfif -v if availableAffected if The version displayed is 11.3.0.2400
-
Confirm the vulnerability trigger conditionThe flaw is triggered when processing a specially crafted PDF file containing a corrupted DCTStream (JPEG image data stream) during image rendering. This occurs when the application opens and renders such a PDF fileAffected if A user opens a malicious PDF file with the vulnerable version 11.3.0.2400
If Lexmark Perceptive Document Filters version 11.3.0.2400 is installed and processes untrusted PDF files, the system is affected by this vulnerability.

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 the vendor-supplied patch or update Lexmark Perceptive Document Filters to a patched version. Until patched, implement file-based defenses such as email/messaging content filtering to block or quarantine untrusted PDF attachments before they reach the vulnerable system.
