The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.","published":"2019-08-13T21:15:12.287Z","modified":"2026-07-08T05:55:11.348420823Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.83433,"percentile":0.99661,"asOf":"2026-09-04"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"golang.org/x/net","fixedVersion":"0.0.0-20190813141303-74dc4d7220e7"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/392108390cef48af647a2e47b7fd5380e050e35ae8d1aa2030254c04%40%3Cusers.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ad3d01e767199c1aed8033bb6b3f5bf98c011c7c536f07a5d34b3c19%40%3Cannounce.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/bde52309316ae798186d783a5e29f4ad1527f61c9219a289d0eee0a7%40%3Cdev.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4BBP27PZGSY6OP6D26E5FW4GZKBFHNU7/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4ZQGHE3WTYLYAYJEIDJVF2FIGQTAYPMC/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CMNFX5MNYRWWIMO4BTKYQCGUDMHO3AXP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYO6E3H34C346D2E443GLXK7OK6KIYIQ/"},{"type":"WEB","url":"https://support.f5.com/csp/article/K98053339?utm_source=f5support&amp%3Butm_medium=RSS"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00038.html"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2019/Aug/16"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/08/20/1"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2594"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2661"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2682"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2690"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2726"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2766"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2769"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2796"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2861"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2925"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2939"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2955"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2966"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3131"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3245"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3265"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3892"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3906"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4018"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4019"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4020"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4021"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4040"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4041"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4042"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4045"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4269"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4273"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4352"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0406"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0727"},{"type":"ADVISORY","url":"https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md"},{"type":"ADVISORY","ur
