| Doc Text: |
A flaw was found in FFmpeg. A heap-based buffer overflow vulnerability exists in the VideoToolbox encoder component when handling video streams whose resolution increases mid-stream without rescaling. By supplying a specially crafted video file, an attacker can cause oversized frames to be copied into undersized memory buffers. This flaw allows an attacker to corrupt application memory, potentially leading to arbitrary code execution or causing the application to crash, resulting in a Denial of Service (DoS).
