| Doc Text: |
A flaw was found in FFmpeg. By supplying a specially crafted video stream whose resolution increases mid-stream, an attacker could trigger a heap-based buffer overflow when media is processed using Intel Quick Sync Video (QSV) encoders without rescaling. This vulnerability occurs due to the reuse of an undersized internal buffer and can lead to arbitrary code execution, memory corruption, or an application crash resulting in a Denial of Service (DoS).
