CVE-2023-49295

Summary

CVE-2023-49295 is a vulnerability affecting the quic-go implementation of the QUIC protocol in Go. An attacker can exploit this issue by sending a large number of PATH_CHALLENGE frames, causing the peer to run out of memory. This occurs because the receiver is required to respond with a PATH_RESPONSE frame for each challenge, but the attacker can prevent these responses from being sent by manipulating the congestion window and RTT estimate. The vulnerability has been addressed in versions 0.37.7, 0.38.2, and 0.39.4 of quic-go.
