If the vendor information element data length is larger than 164 bytes, a heap buffer overflow is triggered in wlc_wpa_plumb_gtk. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions." } ] }, "generator": { "engine": "Vulnogram 0.0.9" }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "ADJACENT_NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.9, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "CHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-122 Heap-based Buffer Overflow" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "url": "https://blog.quarkslab.com/reverse-engineering-broadcom-wireless-chipsets.html", "name": "https://blog.quarkslab.com/reverse-engineering-broadcom-wireless-chipsets.html" }, { "refsource": "MISC", "url": "https://kb.cert.org/vuls/id/166939/", "name": "https://kb.cert.org/vuls/id/166939/" } ] }, "source": { "advisory": "VU#166939", "discovery": "UNKNOWN" } }
