{"id":"CVE-2019-9512","details":"Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. 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.","aliases":["CVE-2019-9514","GHSA-39qc-96h7-956f","GHSA-hgr8-6h9x-f7q9","GO-2022-0536"],"modified":"2026-04-16T04:38:48.757212375Z","published":"2019-08-13T21:15:12.287Z","related":["ALSA-2019:2925","ALSA-2019:4269","ALSA-2019:4273","CGA-hxrg-2m2v-635r","SUSE-SU-2019:14246-1","SUSE-SU-2019:2213-1","SUSE-SU-2019:2214-1","SUSE-SU-2019:2254-1","SUSE-SU-2019:2259-1","SUSE-SU-2019:2260-1","SUSE-SU-2020:0059-1","openSUSE-SU-2019:2000-1","openSUSE-SU-2019:2056-1","openSUSE-SU-2019:2072-1","openSUSE-SU-2019:2085-1","openSUSE-SU-2019:2114-1","openSUSE-SU-2019:2115-1","openSUSE-SU-2019:2130-1","openSUSE-SU-2024:10804-1","openSUSE-SU-2024:10805-1","openSUSE-SU-2024:10901-1","openSUSE-SU-2024:11098-1","openSUSE-SU-2024:11212-1"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/bde52309316ae798186d783a5e29f4ad1527f61c9219a289d0eee0a7%40%3Cdev.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ad3d01e767199c1aed8033bb6b3f5bf98c011c7c536f07a5d34b3c19%40%3Cannounce.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://support.f5.com/csp/article/K98053339?utm_source=f5support&amp%3Butm_medium=RSS"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4BBP27PZGSY6OP6D26E5FW4GZKBFHNU7/"},{"type":"WEB","url":"https://lists.apache.org/thread.html/392108390cef48af647a2e47b7fd5380e050e35ae8d1aa2030254c04%40%3Cusers.trafficserver.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYO6E3H34C346D2E443GLXK7OK6KIYIQ/"},{"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":"ADVISORY","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10296"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/08/20/1"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3906"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Sep/18"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4508"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2726"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4040"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Aug/24"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2594"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2019/Aug/16"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2766"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2955"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00011.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3245"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4018"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4041"},{"type":"ADVISORY","url":"https://kb.cert.org/vuls/id/605641/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4520"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00038.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4021"},{"type":"ADVISORY","url":"https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2690"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3265"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4273"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0727"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190823-0004/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4503"},{"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":"https://access.redhat.com/errata/RHSA-2019:4042"},{"type":"ADVISORY","url":"https://support.f5.com/csp/article/K98053339"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4019"},{"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":
