CVE-2025-3277

An integer overflow can be triggered in SQLite’s `concat_ws()` function. The resulting, truncated integer is then used to allocate a buffer. When SQLite then writes the resulting string to the buffer, it uses the original, untruncated size and thus a wild Heap Buffer overflow of size ~4GB can be triggered. This can result in arbitrary code execution.

Summary		(es) Se puede activar un desbordamiento de entero en la función `concat_ws()` de SQLite. El entero truncado resultante se utiliza para asignar un búfer. Cuando SQLite escribe la cadena resultante en el búfer, utiliza el tamaño original sin truncar, lo que puede provocar un desbordamiento descontrolado del búfer de montón de aproximadamente 4 GB. Esto puede provocar la ejecución de código arbitrario.
