CVE-2026-96611

FFmpeg versions prior to 9.0 are vulnerable to a signed integer overflow in libavformat/mov.c. Specifically, in mov_read_ispe(), uint32_t width and height values from a crafted HEIF ispe box are stored into signed int fields without bounds checking. This allows values exceeding INT_MAX to become ...

CVE-2026-96611

FFmpeg before 9.0 has a signed integer overflow in libavformat/mov.c. In movreadispe, uint32t width/height values from a crafted HEIF ispe box are stored into signed int fields without bounds checking, allowing values exceeding INTMAX to become negative. In readimagegrid, accumulating these value...
