Name of the Vulnerable Software and Affected Versions
AIOHTTP versions prior to 3.14.1
Description
An issue exists in the C parser of the asynchronous HTTP client/server framework where the
max line size check can be bypassed in parts of an HTTP request. When using the optimized C parser, which is the default in pre-built wheels, an attacker can send oversized lines through the HTTP parser to consume an excessive amount of memory, potentially resulting in a Denial of Service (DoS), a condition where a system becomes unavailable to its intended users.Recommendations
Update to version 3.14.1.
