Extended Inquiry Responses (EIRs) are improperly handled, which causes a heap-based buffer overflow during device inquiry. This overflow can be used to overwrite existing functions with arbitrary code. The Reserved for Future Use (RFU) bits are not discarded by eir_handleRx(), and are included in an EIR's length. Therefore, one can exceed the expected 240 bytes, which leads to a heap-based buffer overflow in eir_getReceivedEIR() called by bthci_event_SendInquiryResultEvent(). In order to exploit this bug, an attacker must repeatedly connect to the victim's device in a short amount of time from different source addresses. This will cause the victim's Bluetooth stack to resolve the device names and therefore allocate buffers with attacker-controlled data. Due to the heap corruption, the name will be eventually written to an attacker-controlled location, leading to a write-what-where condition."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-787"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2019-11516", "ASSIGNER": "cve@mitre.org"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 6.8, "accessVector": "NETWORK", "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "authentication": "NONE", "integrityImpact": "PARTIAL", "accessComplexity": "MEDIUM", "availabilityImpact": "PARTIAL", "confidentialityImpact": "PARTIAL"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 6.4, "obtainAllPrivilege": false, "exploitabilityScore": 8.6, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 8.1, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH"}, "impactScore": 5.9, "exploitabilityScore": 2.2}}, "publishedDate": "2020-02-05T17:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:google:android:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2020-04-13T15:15Z"}
