CVE-2025-25473

FFmpeg git master before commit c08d30 was discovered to contain a memory leak in the avformat_free_context function in libavutil/mem.c.

A reachable assertion in FFmpeg git-master commit N-113007-g8d24a28d06 allows attackers to cause a Denial of Service (DoS) via opening a crafted AAC file. (CVE-2025-22919) A heap buffer overflow vulnerability in FFmpeg before commit 4bf784c allows attackers to trigger a memory corruption via supplying a crafted media file in avformat when processing tile grid group streams. This can lead to a Denial of Service (DoS). (CVE-2025-22920) FFmpeg git-master,N-113007-g8d24a28d06 was discovered to contain a segmentation violation via the component /libavcodec/jpeg2000dec.c. (CVE-2025-22921) FFmpeg git master before commit c08d30 was discovered to contain a NULL pointer dereference via the component libavformat/mov.c. (CVE-2025-25473)
