CVE-2025-52456 — HIGH (8.8)

Vulnerability Description

A memory corruption vulnerability exists in the WebP Image Decoding functionality of the SAIL Image Decoding Library v0.9.8. When loading a specially crafted .webp animation an integer overflow can be made to occur when calculating the stride for decoding. Afterwards, this will cause a heap-based buffer to overflow when decoding the image which can lead to remote code execution. An attacker will need to convince the library to read a file to trigger this vulnerability.
