CVE-2023-0933Network attack vector

Heap corruption via PDF integer overflow

Published Feb 22, 2023 · Updated May 5, 2025

Integer overflow in the PDF component of Google Chrome before 110.0.5481.177 allows remote attackers to corrupt heap memory via a crafted PDF file. Google identifies the faulty operation only as an integer overflow in PDF; the underlying parser locus and arithmetic operation remain restricted. Successful exploitation requires user interaction with the crafted PDF and yields heap corruption inside the browser process.
