{"id":"CVE-2025-59530","state":"PUBLISHED","title":"quic-go has Client Crash Due to Premature HANDSHAKE_DONE Frame","description":"quic-go is an implementation of the QUIC protocol in Go. In versions prior to 0.49.0, 0.54.1, and 0.55.0, a misbehaving or malicious server can cause a denial-of-service (DoS) attack on the quic-go client by triggering an assertion failure, leading to a process crash. This requires no authentication and can be exploited during the handshake phase. This was observed in the wild with certain server implementations. quic-go needs to be able to handle misbehaving server implementations, including those that prematurely send a HANDSHAKE_DONE frame. Versions 0.49.0, 0.54.1, and 0.55.0 discard Initial keys when receiving a HANDSHAKE_DONE frame, thereby correctly handling premature HANDSHAKE_DONE frames.","publishedAt":"2025-10-10T16:09:55.227Z","updatedAt":"2025-10-10T16:31:47.457Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["quic-go quic-go"],"affected":[{"vendor":"quic-go","product":"quic-go","versions":[{"version":"< 0.49.1","status":"affected"},{"version":">= 0.5.0, < 0.54.1","status":"affected"}]}],"references":["https://github.com/quic-go/quic-go/security/advisories/GHSA-47m2-4cr7-mhcw","https://github.com/quic-go/quic-go/pull/5354","https://github.com/quic-go/quic-go/blob/v0.55.0/connection.go#L2682-L2685"],"weaknesses":["CWE-617","CWE-755"],"ingestedAt":"2026-10-29T20:09:39.787Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/59xxx/CVE-2025-59530.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-59530","state":"PUBLISHED","datePublished":"2025-10-10T16:09:55.227Z","dateUpdated":"2025-10-10T16:31:47.457Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-09-17T17:04:20.373Z"},"containers":{"cna":{"title":"quic-go has Client Crash Due to Premature HANDSHAKE_DONE Frame","descriptions":[{"lang":"en","value":"quic-go is an implementation of the QUIC protocol in Go.
