Details

As written in the advisory (Markdown source, shown as plain text).

### Summary An out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. ### Impact An attacker controlled server, or possibly an accidental response could trigger a DoS in the client. ### Workaround If unable to upgrade, the Python parser is unaffected and can be used with `AIOHTTP_NO_EXTENSIONS=1`. --- Patch: https://github.com/aio-libs/aiohttp/commit/49f65d54150397892f7bcc4aae887767d51c322d
