Heap corruption via Media Galleries buffer overflow
Published Nov 1, 2022 · Updated Nov 12, 2024
Heap buffer overflow in Media Galleries in Google Chrome before 107.0.5304.62 allows attackers to corrupt heap memory through crafted HTML. Google has not published the specific Media Galleries code path or the incorrect bounds operation that writes beyond the heap buffer. Exploitation requires a user to install a malicious extension and then process attacker-controlled HTML, bounding exposure to extension-enabled browser sessions.
