{"id":"GHSA-c33x-xqrf-c478","summary":"QUIC's Connection ID Mechanism vulnerable to Memory Exhaustion Attack","details":"An attacker can cause its peer to run out of memory 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. 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.\n\nI published a more detailed description of the attack and its mitigation in this blog post: https://seemann.io/posts/2024-03-19-exploiting-quics-connection-id-management/.\nI also presented this attack in the IETF QUIC working group session at IETF 119: https://youtu.be/JqXtYcZAtIA?si=nJ31QKLBSTRXY35U&t=3683\n\nThere's no way to mitigate this attack, please update quic-go to a version that contains the fix.","aliases":["CVE-2024-22189","GO-2024-2682"],"modified":"2026-01-30T01:15:33.047942Z","published":"2024-04-02T14:16:05Z","related":["CGA-5cg8-j3ff-f9wv"],"database_specific":{"github_reviewed_at":"2024-04-02T14:16:05Z","github_reviewed":true,"nvd_published_at":"2024-04-04T15:15:37Z","cwe_ids":["CWE-400","CWE-770"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/quic-go/quic-go/security/advisories/GHSA-c33x-xqrf-c478"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-22189"},{"type":"WEB","url":"https://github.com/quic-go/quic-go/commit/4a99b816ae3ab03ae5449d15aac45147c85ed47a"},{"type":"PACKAGE","url":"https://github.com/quic-go/quic-go"},{"type":"WEB","url":"https://seemann.io/posts/2024-03-19-exploiting-quics-connection-id-management"},{"type":"WEB","url":"https://www.youtube.com/watch?v=JqXtYcZAtIA&t=3683s"}],"affected":[{"package":{"name":"github.com/quic-go/quic-go","ecosystem":"Go","purl":"pkg:golang/github.com/quic-go/quic-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.42.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/04/GHSA-c33x-xqrf-c478/GHSA-c33x-xqrf-c478.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
