Use-after-free vulnerability in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764.

Security readout for executives and security teams

A malicious PDF can crash older PDF or font-processing software that includes t1lib. The confirmed impact in the CVE source is denial of service, not proven system takeover for this specific CVE. Exposure is most likely in legacy Linux or Unix systems, PDF-processing pipelines, or desktop tools that still use affected t1lib, Xpdf, teTeX, or vendor packages. Modern systems are exposed only if these older components or unpatched downstream builds remain installed. Treat this as a legacy software hygiene issue unless vulnerable PDF processing is internet-facing or business-critical. Prioritize systems that automatically ingest PDFs from customers, email, web uploads, or external partners. Mitigation focus: Update Xpdf to 3.02pl6 or later where applicable.; Apply vendor security updates for t1lib and downstream packages.; Check OS vendor advisories for supported backported fixes..
