Summary
As of quinn-proto 0.11, it is possible for a server to
accept(),retry(),refuse(), orignore()anIncomingconnection. However, callingretry()on an unvalidated connection exposes the server to a likely panic in the following situations:- Calling
refuseorignoreon the resulting validated connection, if a duplicate initial packet is received- This issue can go undetected until a server's
refuse()/ignore()code path is exercised, such as to stop a denial of service attack.
- This issue can go undetected until a server's
- Accepting when the initial packet for the resulting validated connection fails to decrypt or exhausts connection IDs, if a similar initial packet that successfully decrypts and doesn't exhaust connection IDs is received.
- This issue can go undetected if clients are well-behaved.
The former situation was observed in a real application, while the latter is only theoretical.
