Summary
AIOHTTP's HTTP Parser auto_decompress feature is vulnerable to zip bomb
Details

Summary

A zip bomb can be used to execute a DoS against the aiohttp server.

Impact

An attacker may be able to send a compressed request that when decompressed by aiohttp could exhaust the host's memory.

Patch: https://github.com/aio-libs/aiohttp/commit/2b920c39002cee0ec5b402581779bbaaf7c9138a
