functions in its Firequalizer filter and in the HTTP Live Streaming (HLS)
implementation, leading to a NULL pointer dereference. If a user was
tricked into loading a crafted media file, a remote attacker could
possibly use this issue to make FFmpeg crash, resulting in a denial
of service. (CVE-2023-6603, CVE-2025-10256)

It was discovered that FFmpeg did not enforce an input format before
triggering the HTTP demuxer. A remote attacker could possibly use this
issue to perform a Server-Side Request Forgery (SSRF) attack.
(CVE-2025-6605)

It was discovered that FFmpeg incorrectly handled memory allocation in the
ALS audio decoder. If a user was tricked into loading a crafted media file,
a remote attacker could possibly use this issue to make FFmpeg crash,
resulting in a denial of service. (CVE-2025-7700)

It was discovered that FFmpeg incorrectly handled memory in the JPEG 2000
decoder, which could lead to a heap buffer overflow. If a user or
application were tricked into opening a specially crafted file, an
attacker could possibly use this issue to cause a denial of service
or leak sensitive information. (CVE-2025-9951)");
