CVE-2022-41844Public exploit

Application crash via out-of-bounds write during object fetch

Published Sep 30, 2022 · Updated May 20, 2025

Out-of-bounds write in Xpdf 4.04 allows context-dependent attackers to crash the application by opening a crafted PDF file. XRef::fetch in xpdf/XRef.cc writes beyond the intended buffer while resolving an attacker-controlled PDF object reference, terminating the process. Successful exploitation requires a user to open the file, and the documented consequence is an application crash without confidentiality or integrity impact.
