CVE-2024-7018Network attack vector

Heap corruption via crafted PDF processing

Published Sep 23, 2024 · Updated Sep 24, 2024

Heap buffer overflow in Google Chrome's PDF component before 124.0.6367.78 allows remote attackers to corrupt heap memory with a crafted PDF file. Google has not published the affected PDF-processing routine or the incorrect bounds operation that permits the heap overwrite. Rendering an attacker-supplied PDF is required; the public record does not identify the resulting post-corruption capability.
