GHSA-6mq8-rvhq-8wgg: AIOHTTP's HTTP Parser auto_decompress feature is vulnerable to zip bomb
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
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
