CVE-2017-2821: An exploitable use-after-free exists in the PDF parsing functionality of Lexmark Perspective Document Filte...

Security readout for executives and security teams

This flaw affects Lexmark Perceptive Document Filters when parsing PDFs. A malicious PDF could trigger a memory safety bug and allow code execution. Business risk is highest where this software processes PDFs from email, portals, uploads, or other untrusted sources. Organizations are likely exposed if they run the listed x86 versions of Lexmark Perceptive Document Filters and use them to parse or transform PDFs, especially documents received from external users, email, customer uploads, or automated ingestion pipelines. Treat this as high priority where affected systems handle outside PDFs. The weakness can lead to code execution, so remediation should focus first on document workflows that receive files from customers, partners, email, or public upload paths. Mitigation focus: Identify any systems running the affected Lexmark Perceptive Document Filters versions.; Check Lexmark and Talos guidance for fixed versions or vendor-approved remediation.; Avoid processing untrusted PDFs through affected components until remediated..
