{"id":"CVE-2016-4439","details":"The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors.","modified":"2026-05-18T05:48:33.431960043Z","published":"2016-05-20T14:59:07.450Z","related":["SUSE-SU-2016:1560-1","SUSE-SU-2016:1698-1","SUSE-SU-2016:1703-1","SUSE-SU-2016:1785-1","SUSE-SU-2016:2093-1","SUSE-SU-2016:2100-1","SUSE-SU-2016:2528-1","SUSE-SU-2016:2533-1","SUSE-SU-2016:2725-1","openSUSE-SU-2024:10196-1","openSUSE-SU-2024:10233-1","openSUSE-SU-2024:10285-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"last_affected":"12.04"},{"last_affected":"14.04"},{"last_affected":"16.04"}],"vendor_product":"canonical:ubuntu_linux","source":"CPE_FIELD","cpes":["cpe:2.3:o:canonical:ubuntu_linux:12.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*"]},{"extracted_events":[{"last_affected":"8.0"}],"vendor_product":"debian:debian_linux","source":"CPE_FIELD","cpes":["cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*"]}]},"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/90760"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3047-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3047-2"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201609-01"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1337502"},{"type":"FIX","url":"http://www.openwall.com/lists/oss-security/2016/05/19/3"},{"type":"FIX","url":"https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg03273.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/qemu/qemu","events":[{"introduced":"0"},{"last_affected":"bfc766d38e1fae5767d43845c15c79ac8fa6d6af"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.6.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*"}}],"versions":["v2.6.0","v2.6.0-rc5","v2.6.0-rc4","v2.6.0-rc3","v2.6.0-rc2","v2.6.0-rc1","v2.6.0-rc0","v2.5.0","v2.5.0-rc4","v2.5.0-rc3","v2.5.0-rc2","v2.5.0-rc1","v2.5.0-rc0","v2.4.0","v2.4.0-rc4","v2.4.0-rc3","v2.3.0","v2.4.0-rc2","v2.4.0-rc1","v2.4.0-rc0","v2.3.0-rc4","v2.3.0-rc3","v2.3.0-rc2","v2.3.0-rc1","v2.3.0-rc0","v2.2.0","v2.2.0-rc3","v2.2.0-rc5","v2.2.0-rc4","v2.2.0-rc2","v2.2.0-rc1","v2.2.0-rc0","v2.1.0","v2.1.0-rc5","v2.1.0-rc4","v2.1.0-rc2","v2.1.0-rc3","v2.0.0","v2.1.0-rc1","v2.1.0-rc0","v2.0.0-rc3","v2.0.0-rc2","v2.0.0-rc1","v2.0.0-rc0","v1.7.0","v1.7.0-rc2","v1.7.0-rc1","v1.7.0-rc0","v1.6.0","v1.6.0-rc3","v1.6.0-rc2","v1.6.0-rc1","v1.6.0-rc0","v1.5.0","v1.5.0-rc3","v1.5.0-rc2","v1.5.0-rc1","v1.5.0-rc0","v1.4.0","v1.4.0-rc2","v1.4.0-rc1","v1.4.0-rc0","v1.3.0","v1.3.0-rc2","v1.3.0-rc1","v1.3.0-rc0","v1.2.0","v1.2.0-rc3","v1.2.0-rc2","v1.2.0-rc1","v1.2.0-rc0","v1.1.0","v1.1.0-rc4","v1.1.0-rc3","v1.1.0-rc2","v1.1-rc2","v1.1-rc1","v1.1-rc0","v1.0","v1.0-rc4","v1.0-rc3","v1.0-rc2","v1.0-rc1","v1.0-rc0","v0.14.0-rc0","v0.13.0-rc0","v0.12.0-rc0","v0.11.0-rc0","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.0","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2016-4439.json"}},{"ranges":[{"type":"GIT","repo":"https://gitlab.com/qemu-project/qemu","events":[{"introduced":"0"},{"last_affected":"bfc766d38e1fae5767d43845c15c79ac8fa6d6af"}],"database_specific":{"cpe":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"2.6.0"}]}}],"versions":["v2.6.0","v2.6.0-rc5","v2.6.0-rc4","v2.6.0-rc3","v2.6.0-rc2","v2.6.0-rc1","v2.6.0-rc0","v2.5.0","v2.5.0-rc4","v2.5.0-rc3","v2.5.0-rc2","v2.5.0-rc1","v2.5.0-rc0","v2.4.0","v2.4.0-rc4","v2.4.0-rc3","v2.3.0","v2.4.0-rc2","v2.4.0-rc1","v2.4.0-rc0","v2.3.0-rc4","v2.3.0-rc3","v2.3.0-rc2","v2.3.0-rc1","v2.3.0-rc0","v2.2.0","v2.2.0-rc3","v2.2.0-rc5","v2.2.0-rc4","v2.2.0-rc2","v2.2.0-rc1","v2.2.0-rc0","v2.1.0","v2.1.0-rc5","v2.1.0-rc4","v2.1.0-rc2","v2.1.0-rc3","v2.0.0","v2.1.0-rc1","v2.1.0-rc0","v2.0.0-rc3","v2.0.0-rc2","v2.0.0-rc1","v2.0.0-rc0","v1.7.0","v1.7.0-rc2","v1.7.0-rc1","v1.7.0-rc0","v1.6.0","v1.6.0-rc3","v1.6.0-rc2","v1.6.0-rc1","v1.6.0-rc0","v1.5.0","v1.5.0-rc3","v1.5.0-rc2","v1.5.0-rc1","v1.5.0-rc0","v1.4.0","v1.4.0-rc2","v1.4.0-rc1","v1.4.0-rc0","v1.3.0","v1.3.0-rc2","v1.3.0-rc1","v1.3.0-rc0","v1.2.0","v1.2.0-rc3","v1.2.0-rc2","v1.2.0-rc1","v1.2.0-rc0","v1.1.0","v1.1.0-rc4","v1.1.0-rc3","v1.1.0-rc2","v1.1-rc2","v1.1-rc1","v1.1-rc0","v1.0","v1.0-rc4","v1.0-rc3","v1.0-rc2","v1.0-rc1","v1.0-rc0","v0.14.0-rc0","v0.13.0-rc0","v0.12.0-rc0","v0.11.0-rc0","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.0","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2016-4439.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
