{"id":"CVE-2020-9490","details":"Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via \"H2Push off\" will mitigate this vulnerability for unpatched servers.","aliases":["BIT-apache-2020-9490"],"modified":"2026-05-28T04:06:19.585029408Z","published":"2020-08-07T16:15:12.043Z","related":["SUSE-SU-2020:2311-1","SUSE-SU-2020:2344-1","SUSE-SU-2020:2450-1","SUSE-SU-2020:3067-1","openSUSE-SU-2020:1285-1","openSUSE-SU-2020:1293-1","openSUSE-SU-2020:1792-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"8.2.0"},{"last_affected":"8.2.2"}],"source":"CPE_RANGE","cpes":["cpe:2.3:a:oracle:communications_element_manager:*:*:*:*:*:*:*:*"],"vendor_product":"oracle:communications_element_manager"},{"source":"CPE_RANGE","extracted_events":[{"introduced":"8.2.0"},{"last_affected":"8.2.2"}],"cpes":["cpe:2.3:a:oracle:communications_session_report_manager:*:*:*:*:*:*:*:*"],"vendor_product":"oracle:communications_session_report_manager"},{"source":"CPE_RANGE","extracted_events":[{"introduced":"8.2.0"},{"last_affected":"8.2.2"}],"cpes":["cpe:2.3:a:oracle:communications_session_route_manager:*:*:*:*:*:*:*:*"],"vendor_product":"oracle:communications_session_route_manager"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"16.04"},{"last_affected":"18.04"},{"last_affected":"20.04"}],"cpes":["cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:esm:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:20.04:*:*:*:lts:*:*:*"],"vendor_product":"canonical:ubuntu_linux"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"10.0"}],"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*"],"vendor_product":"debian:debian_linux"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"31"},{"last_affected":"32"}],"cpes":["cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:32:*:*:*:*:*:*:*"],"vendor_product":"fedoraproject:fedora"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"15.1"},{"last_affected":"15.2"}],"cpes":["cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*","cpe:2.3:o:opensuse:leap:15.2:*:*:*:*:*:*:*"],"vendor_product":"opensuse:leap"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"12.4.0.0"}],"cpes":["cpe:2.3:a:oracle:enterprise_manager_ops_center:12.4.0.0:*:*:*:*:*:*:*"],"vendor_product":"oracle:enterprise_manager_ops_center"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"11.1.2.4"}],"cpes":["cpe:2.3:a:oracle:hyperion_infrastructure_technology:11.1.2.4:*:*:*:*:*:*:*"],"vendor_product":"oracle:hyperion_infrastructure_technology"},{"extracted_events":[{"last_affected":"17.1"},{"last_affected":"17.2"},{"last_affected":"17.3"}],"source":"CPE_STRING","cpes":["cpe:2.3:a:oracle:instantis_enterprisetrack:17.1:*:*:*:*:*:*:*","cpe:2.3:a:oracle:instantis_enterprisetrack:17.2:*:*:*:*:*:*:*","cpe:2.3:a:oracle:instantis_enterprisetrack:17.3:*:*:*:*:*:*:*"],"vendor_product":"oracle:instantis_enterprisetrack"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.8"}],"cpes":["cpe:2.3:a:oracle:zfs_storage_appliance_kit:8.8:*:*:*:*:*:*:*"],"vendor_product":"oracle:zfs_storage_appliance_kit"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*"],"vendor_product":"redhat:enterprise_linux"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.1"},{"last_affected":"8.2"},{"last_affected":"8.4"},{"last_affected":"8.6"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_eus:8.1:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:8.2:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:8.4:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:8.6:*:*:*:*:*:*:*"],"vendor_product":"redhat:enterprise_linux_eus"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_for_ibm_z_systems:8.0:*:*:*:*:*:*:*"],"vendor_product":"redhat:enterprise_linux_for_ibm_z_systems"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.1"},{"last_affected":"8.2"},{"last_affected":"8.4"},{"last_affected":"8.6"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_for_ibm_z_systems_eus:8.1:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_for_ibm_z_systems_eus:8.2:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_for_ibm_z_systems_eus:8.4:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_for_ibm_z_systems_eus:8.6:*:*:*:*:*:*:*"],"vendor_product":"redhat:enterprise_linux_for_ibm_z_systems_eus"},{"source":"CPE_STRING","extracted_events":[{"last_affected":"8.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_for_power_little_endian:8.0:*:*:*:*:*:*:*"],"vendor_product":"redhat:enterprise_linux_for_power_little_endian"},{"extracted_events":[{"last_affected":"8.1"},{"last_affected":"8.2"},{"last_affected":"8.4"},{"last_affected":"8.6"}],"source":"CPE_STRING","cpes":["cpe:2.3:o:redhat:enterprise_linux_for_power_little_endian_eus:8.1:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_for_power_little_endian_eus:8.2:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_for_power_little_endian_eus:8.4:*:*:*:*:*:*:*","cpe:2.3:o:redhat:ent
