CVE-2024-5197Public exploitNetwork attack vector

Memory corruption via unchecked image size arithmetic

Published Jun 3, 2024 · Updated Feb 13, 2025

Integer overflow in libvpx before 1.14.1 allows attackers to corrupt image metadata through oversized dimensions or alignment values. img_alloc_helper computes strides, allocation sizes, and plane offsets with arithmetic that wraps before values are stored in vpx_image_t. Reachability requires a consuming application to pass attacker-influenced extreme values; invalid strides and plane offsets can corrupt memory or crash that process.
