### Summary Payload resources are not closed correctly when a client disconnects in the middle of a write. ### Impact If a payload is using an open file or similar limited resource, then an attacker may be able to cause resource starvation temporarily until garbage collection or similar closes the file. ----- Patch: https://github.com/aio-libs/aiohttp/commit/a762eda5242f6490d6ba667533193f8b473ad587
