quiche vulnerable to unlimited resource allocation by QUIC CRYPTO frames flooding

Published: 3/13/2024Modified: 3/13/2026

Description

### Impact Cloudflare Quiche (through version 0.19.1/0.20.0) was affected by an unlimited resource allocation vulnerability causing rapid increase of memory usage of the system running quiche server or client. A remote attacker could take advantage of this vulnerability by repeatedly sending an unlimited number of 1-RTT CRYPTO frames after previously completing the QUIC handshake. Exploitation was possible for the duration of the connection which could be extended by the attacker. ### Patches Quiche 0.19.2 and 0.20.1 are the earliest versions containing the fix for this issue.
