Executive Summary

This vulnerability is an integer overflow in the libavfilter/vf_scale.c component of FFmpeg version N-122528-gdd2976b9e1. An integer overflow occurs when a calculation exceeds the maximum value an integer can hold, causing unexpected behavior. In this case, it can lead to a Denial of Service (DoS) when a specially crafted video file is processed.

Impact Analysis

The vulnerability allows attackers to cause a Denial of Service by supplying a malicious video file. This could crash the FFmpeg application or the system processing the file, disrupting normal operations and potentially leading to service unavailability.

Mitigation Strategies

Update FFmpeg to a patched version that fixes the integer overflow in libavfilter/vf_scale.c. Avoid processing untrusted video files until the update is applied.
