{"schema_version":"1.7.5","id":"CVE-2020-10702","published":"2020-06-04T18:15:14.157Z","modified":"2026-07-08T20:30:10.767889Z","related":["openSUSE-SU-2024:11287-1"],"details":"A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/qemu/qemu","events":[{"introduced":"131b9a05705636086699df15d4a6d328bb2585e8"},{"fixed":"fdd76fecdde1ad444ff4deb7f1c4f7e4a1ef97d6"}],"database_specific":{"cpe":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.0.0"},{"fixed":"5.0.0"}],"source":"CPE_RANGE"}}],"versions":["v4.2.0","v5.0.0-rc4","v5.0.0-rc3","v5.0.0-rc2","v5.0.0-rc1","v5.0.0-rc0","v4.2.0-rc5","v4.2.0-rc4","v4.2.0-rc3","v4.2.0-rc2","v4.2.0-rc1","v4.2.0-rc0","v4.1.0","v4.0.0","v4.1.0-rc5","v4.1.0-rc4","v4.1.0-rc3","v4.1.0-rc2","v4.1.0-rc1","v4.1.0-rc0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-10702.json"}},{"ranges":[{"type":"GIT","repo":"https://gitlab.com/qemu-project/qemu","events":[{"introduced":"131b9a05705636086699df15d4a6d328bb2585e8"},{"fixed":"fdd76fecdde1ad444ff4deb7f1c4f7e4a1ef97d6"}],"database_specific":{"cpe":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.0.0"},{"fixed":"5.0.0"}],"source":"CPE_RANGE"}}],"versions":["v4.2.0","v5.0.0-rc4","v5.0.0-rc3","v5.0.0-rc2","v5.0.0-rc1","v5.0.0-rc0","v4.2.0-rc5","v4.2.0-rc4","v4.2.0-rc3","v4.2.0-rc2","v4.2.0-rc1","v4.2.0-rc0","v4.1.0","v4.0.0","v4.1.0-rc5","v4.1.0-rc4","v4.1.0-rc3","v4.1.0-rc2","v4.1.0-rc1","v4.1.0-rc0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-10702.json"}}],"references":[{"type":"WEB","url":"https://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=de0b1bae6461f67243282555475f88b2384a1eb9"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20200724-0007/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10702"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
