{"id":"CVE-2019-9516","details":"Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.","modified":"2026-02-24T11:33:55.267021Z","published":"2019-08-13T21:15:12.583Z","related":["ALSA-2019:2799","ALSA-2019:2925","MGASA-2019-0342","MGASA-2020-0372","SUSE-SU-2019:14246-1","SUSE-SU-2019:2254-1","SUSE-SU-2019:2259-1","SUSE-SU-2019:2260-1","SUSE-SU-2019:2309-1","SUSE-SU-2019:2559-1","SUSE-SU-2020:0059-1","openSUSE-SU-2019:2114-1","openSUSE-SU-2019:2115-1","openSUSE-SU-2019:2120-1","openSUSE-SU-2019:2264-1","openSUSE-SU-2024:11092-1"],"references":[{"type":"WEB","url":"https://kb.cert.org/vuls/id/605641/"},{"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/BP556LEG3WENHZI5TAQ6ZEBFTJB4E2IS/"},{"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/H472D5HPXN6RRXCNFML3BK5OYC52CXF2/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/POPAEC4FWL4UU4LDEGPY5NPALU24FFQD/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TAZZEVTCN2B4WT6AIBJ7XGYJMBTORJU5/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XHTKU7YQ5EEP2XNSAV4M4VJ7QCBOJMOD/"},{"type":"WEB","url":"https://support.f5.com/csp/article/K02591030?utm_source=f5support&amp%3Butm_medium=RSS"},{"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/msg00035.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00014.html"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2019/Aug/16"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2745"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2746"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2775"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2799"},{"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-2019:2946"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2950"},{"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-2019:3932"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3933"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3935"},{"type":"ADVISORY","url":"https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md"},{"type":"ADVISORY","url":"https://kb.cert.org/vuls/id/605641/"},{"type":"ADVISORY","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10296"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Aug/24"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Aug/40"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190823-0002/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190823-0005/"},{"type":"ADVISORY","url":"https://support.f5.com/csp/article/K02591030"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4099-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4505"},{"type":"ADVISORY","url":"https://www.synology.com/security/advisory/Synology_SA_19_33"},{"type":"ARTICLE","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html"},{"type":"ARTICLE","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html"},{"type":"ARTICLE","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html"},{"type":"ARTICLE","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00014.html"},{"type":"ARTICLE","url":"http://seclists.org/fulldisclosure/2019/Aug/16"},{"type":"ARTICLE","url":"https://seclists.org/bugtraq/2019/Aug/24"},{"type":"ARTICLE","url":"https://seclists.org/bugtraq/2019/Aug/40"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nodejs/node","events":[{"introduced":"0d8021e5a4cf0a6aa3a700a361f6d42c2894f2ba"},{"fixed":"5744b466c45d5324c60f122b02681813d4496749"},{"introduced":"2f45ad8060e13d5ac912335096d21526f2f9602b"},{"fixed":"787378879acfb212ed4ff824bf9f767a24a5cb43"},{
