{"id":"CVE-2017-15118","details":"A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.","modified":"2026-05-19T12:00:44.227249570Z","published":"2018-07-27T21:29:00.337Z","related":["openSUSE-SU-2024:11287-1"],"database_specific":{"unresolved_ranges":[{"vendor_product":"canonical:ubuntu_linux","extracted_events":[{"last_affected":"14.04"},{"last_affected":"16.04"},{"last_affected":"17.10"}],"cpes":["cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:17.10:*:*:*:*:*:*:*"],"source":"CPE_FIELD"},{"vendor_product":"redhat:enterprise_linux","extracted_events":[{"last_affected":"7.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD"}]},"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/101975"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:1104"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3575-1/"},{"type":"FIX","url":"http://www.openwall.com/lists/oss-security/2017/11/28/8"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-15118"},{"type":"FIX","url":"https://lists.gnu.org/archive/html/qemu-devel/2017-11/msg05045.html"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/43194/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/qemu/qemu","events":[{"introduced":"0"},{"fixed":"0a0dc59d27527b78a195c2d838d28b7b49e5a639"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.11"}],"cpe":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*","source":"CPE_FIELD"}}],"versions":["v2.11.0-rc5","v2.11.0-rc4","v2.11.0-rc3","v2.11.0-rc2","v2.11.0-rc1","v2.11.0-rc0","v2.10.0","v2.10.0-rc4","v2.10.0-rc3","v2.10.0-rc2","v2.10.0-rc1","v2.9.0","v2.10.0-rc0","v2.9.0-rc5","v2.9.0-rc4","v2.9.0-rc3","v2.9.0-rc2","v2.9.0-rc1","v2.8.0","v2.9.0-rc0","v2.8.0-rc4","v2.8.0-rc3","v2.8.0-rc2","v2.8.0-rc1","v2.8.0-rc0","v2.7.0","v2.7.0-rc5","v2.7.0-rc4","v2.7.0-rc3","v2.7.0-rc2","v2.6.0","v2.7.0-rc1","v2.7.0-rc0","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-2017-15118.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
