Severity ?
Summary
An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks.

El controlador de netback de Linux permite a los frontends controlar el mapeo de las peticiones de colas de peticiones. Cuando se procesa una solicitud para establecer o cambiar este mapeo, faltaba alguna validaci\u00f3n de entrada (por ejemplo, para un desbordamiento de un n\u00famero entero) o era defectuosa, lo que llevaba al acceso OOB en el manejo de hashes. Un frontend malicioso o con errores puede hacer que el backend (normalmente privilegiado) haga accesos a la memoria fuera de l\u00edmites, lo que puede resultar en uno o m\u00e1s escalados de privilegios, denegaciones de servicio (DoS) o fugas de informaci\u00f3n.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:L/AC:L/Au:S/C:C/I:C/A:C\",\"accessVector\":\"LOCAL\",\"accessComplexity\":\"LOW\",\"authentication\":\"SINGLE\",\"confidentialityImpact\":\"COMPLETE\",\"integrityImpact\":\"COMPLETE\",\"availabilityImpact\":\"COMPLETE\",\"baseScore\":6.8},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":3.1,\"impactScore\":10.0,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-125\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:xen:xen:*:*:*:*:*:*:*:*\",\"versionEndIncluding\":\"4.11.0\",\"matchCriteriaId\":\"CDF60B9D-F0FE-401D-9864-7A70BE5631DD\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.7\",\"versionEndExcluding\":\"4.9.133\",\"matchCriteriaId\":\"73ABE4D9-7599-4DA0-B3E3-8A903FB370FB\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.10\",\"versionEndExcluding\":\"4.14.76\",\"matchCriteriaId\":\"8D285C7D-A19B-4F9C-8D23-7B318C8E1207\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.15\",\"versionEndExcluding\":\"4.18.14\",\"matchCriteriaId\":\"7085CAAC-A121-419C-99B3-D78D40981063\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*\",\"matchCriteriaId\":\"B5A6F2F3-4894-4392-8296-3B8DD2679084\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*\",\"matchCriteriaId\":\"F7016A2A-8365-4F1A-89A2-7A19F2BCAE5B\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*\",\"matchCriteriaId\":\"23A7C53F-B80F-4E6A-AFA9-58EEA84BE11D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:18.10:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"07C312A0-CD2C-4B9C-B064-6409B25C278F\"}]}]}],\"references\":[{\"url\":\"http://xenbits.xen.org/xsa/advisory-270.html\",\"source\":\"cve@mitre.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://bugs.chromium.org/p/project-zero/issues/detail?id=1607\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html\",\"source\":\"cve@mitre.org\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/3819-1/\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/3820-1/\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/3820-2/\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/3820-3/\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://www.debian.org/security/2018/dsa-4313\",\"source\":\"cve@mitre.org\",\"tags\":[\"Third Party Advisory\"]}]}}"
