Fixed In Version: quic-go 0.42.0
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in quic-go. This issue may allow an attacker to trigger a denial of service by sending a large number of NEW_CONNECTION_ID frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a RETIRE_CONNECTION_ID frame, but the attacker can prevent the receiver from sending out the vast majority of these RETIRE_CONNECTION_ID frames by selectively acknowledging received packets and collapsing the peers congestion window and by manipulating the peer's RTT estimate.

Description Robb Gatica 2024-04-04 19:36:02 UTC 
quic-go is an implementation of the QUIC protocol in Go. Prior to version 0.42.0, an attacker can cause its peer to run out of memory sending a large number of `NEW_CONNECTION_ID` frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a `RETIRE_CONNECTION_ID` frame. The attacker can prevent the receiver from sending out (the vast majority of) these `RETIRE_CONNECTION_ID` frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. Version 0.42.0 contains a patch for the issue. No known workarounds are available.
