Heap buffer overflow via wrapped image allocation arithmetic
Published Jun 5, 2024 · Updated Feb 13, 2025
Integer overflow in Alliance for Open Media libaom before 3.9.0 allows remote attackers to corrupt heap memory via crafted image dimensions. img_alloc_helper computes aligned dimensions, byte strides, buffer sizes, and plane offsets without rejecting values that wrap unsigned arithmetic. An application must pass attacker-controlled width, height, or alignment values through the public image-allocation APIs; later image access can crash the process or execute arbitrary code.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
