libvpx: A flaw was found in libvpx. When creating images, libvpx trusts the width, height, and alignment of the user input. However, it does not properly validate the provided values. This flaw allows an attacker to craft user inputs or trick the user into opening crafted files, where these types of values are invalid, leading to integer overflows during memory allocation procedures. A successful full attack leads to the targeted application crashing, resulting in a denial of service or memory corruption, which results in data integrity issues.(CVE-2024-5197)

This issue occurs when processing certain specially formatted video data via a crafted HTML page, allowing an attacker to crash or remotely execute arbitrary code in an application, such as a web browser that is compiled with this library.(CVE-2023-44488)
