| Título | libvips (libvips project) libvips 8.19.0 Integer Overflow to Buffer Overflow |
|---|
| Descripción | In vips_source_read_to_memory() (called via vips_source_map()), a 64-bit source->length is used to size a GByteArray via g_byte_array_set_size() (32-bit guint). For sources larger than G_MAXUINT (>4GiB), the allocation truncates but the subsequent read loop writes up to the full 64-bit length, causing a heap-buffer-overflow. Triggered when libvips processes a seekable VipsSource with length >4GiB and uses the read-to-memory fallback (e.g., when mmap() is unavailable/fails). |
