Summary

CVE-2023-4863 (CVSS score: 8.8), also known as the heap buffer overflow in Chrome libWebP, is a client-side vulnerability. This means that the end user of the affected application is at risk. The vulnerability arises from an exploitation involving the writing of more data to a dynamically allocated memory space (heap buffer) than it can hold, using crafted HTML. This vulnerability could lead to a crash or enable the exploiter to execute arbitrary code on the end user's system.
