CVE-2022-41842Public exploit

Application crash via gfseek out-of-bounds write

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. The failure occurs in gfseek in goo/gfile.cc, but public material does not disclose which PDF field drives the invalid write or which bounds check is absent. Successful exploitation requires user interaction with the crafted file and interrupts only the affected Xpdf process.
