{"id":"UBUNTU-CVE-2022-30591","details":"** DISPUTED ** quic-go through 0.27.0 allows remote attackers to cause a denial of service (CPU consumption) via a Slowloris variant in which incomplete QUIC or HTTP/3 requests are sent. This occurs because mtu_discoverer.go misparses the MTU Discovery service and consequently overflows the probe timer. NOTE: the vendor's position is that this behavior should not be listed as a vulnerability on the CVE List.","modified":"2022-07-06T12:15:00Z","published":"2022-07-06T12:15:00Z","withdrawn":"2025-06-23T15:55:02Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-30591"},{"type":"REPORT","url":"https://github.com/lucas-clemente/quic-go/blob/84e03e59760ceee37359688871bb0688fcc4e98f/mtu_discoverer.go"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-30591"}],"affected":[{"package":{"name":"golang-github-lucas-clemente-quic-go","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-lucas-clemente-quic-go"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.18.0-3","0.24.0-1","0.25.0-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-30591.json"}},{"package":{"name":"golang-github-lucas-clemente-quic-go","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-lucas-clemente-quic-go"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.37.4-1","0.38.2-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-30591.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"}]}
