{"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":"2026-06-06T04:00:22.248573746Z","published":"2019-08-13T21:15:12.583Z","related":["ALSA-2019:2799","ALSA-2019:2925","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"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"1.9.5"},{"fixed":"1.16.1"},{"introduced":"1.17.0"},{"last_affected":"1.17.2"}],"source":"CPE_RANGE","vendor_product":"f5:nginx","cpes":["cpe:2.3:a:f5:nginx:*:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:mcafee:web_gateway:*:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"7.7.2.0"},{"fixed":"7.7.2.24"},{"introduced":"7.8.2.0"},{"fixed":"7.8.2.13"},{"introduced":"8.1.0"},{"fixed":"8.2.0"}],"source":"CPE_RANGE","vendor_product":"mcafee:web_gateway"},{"extracted_events":[{"last_affected":"16.04"},{"last_affected":"18.04"},{"last_affected":"19.04"}],"source":"CPE_STRING","vendor_product":"canonical:ubuntu_linux","cpes":["cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*"]},{"vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"9.0"},{"last_affected":"10.0"},{"last_affected":"9.0"},{"last_affected":"10.0"}],"source":"CPE_STRING"},{"extracted_events":[{"last_affected":"30"},{"last_affected":"29"},{"last_affected":"30"},{"last_affected":"32"}],"source":"CPE_STRING","vendor_product":"fedoraproject:fedora","cpes":["cpe:2.3:o:fedoraproject:fedora:29:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:32:*:*:*:*:*:*:*"]},{"extracted_events":[{"last_affected":"15.0"},{"last_affected":"15.1"}],"source":"CPE_STRING","vendor_product":"opensuse:leap","cpes":["cpe:2.3:o:opensuse:leap:15.0:*:*:*:*:*:*:*","cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*"]},{"vendor_product":"oracle:graalvm","cpes":["cpe:2.3:a:oracle:graalvm:19.2.0:*:*:*:enterprise:*:*:*"],"extracted_events":[{"last_affected":"19.2.0"}],"source":"CPE_STRING"},{"cpes":["cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"8.0"}],"source":"CPE_STRING","vendor_product":"redhat:enterprise_linux"},{"source":"CPE_STRING","vendor_product":"redhat:jboss_core_services","cpes":["cpe:2.3:a:redhat:jboss_core_services:1.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"1.0"}]},{"extracted_events":[{"last_affected":"7.2.0"},{"last_affected":"7.3.0"}],"source":"CPE_STRING","vendor_product":"redhat:jboss_enterprise_application_platform","cpes":["cpe:2.3:a:redhat:jboss_enterprise_application_platform:7.2.0:*:*:*:*:*:*:*","cpe:2.3:a:redhat:jboss_enterprise_application_platform:7.3.0:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:redhat:openshift_service_mesh:1.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"1.0"}],"source":"CPE_STRING","vendor_product":"redhat:openshift_service_mesh"},{"vendor_product":"redhat:quay","cpes":["cpe:2.3:a:redhat:quay:3.0.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"3.0.0"}],"source":"CPE_STRING"},{"source":"CPE_STRING","vendor_product":"redhat:software_collections","cpes":["cpe:2.3:a:redhat:software_collections:1.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"1.0"}]},{"cpes":["cpe:2.3:o:synology:diskstation_manager:6.2:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"6.2"}],"source":"CPE_STRING","vendor_product":"synology:diskstation_manager"}]},"references":[{"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/m
