The bounds check in read_key() was performed after using the value, instead of before. If 'key-method 1' is used, this allowed an attacker to send a malformed packet to trigger a stack buffer overflow. Note that 'key-method 1' has been replaced by 'key method 2' as the default in OpenVPN 2.0 (CVE-2017-12166).

If\n'key-method 1' is used, this allowed an attacker to send a malformed\npacket to trigger a stack buffer overflow.\nNote that 'key-method 1' has been replaced by 'key method 2' as the\ndefault in OpenVPN 2.0 (released on 2005-04-17), and explicitly\ndeprecated in 2.4 and marked for removal in 2.5. This should limit the\namount of users impacted by this issue.\n\nImpact\n======\n\nA remote attacker is able to execute arbitrary code on the affected\nhost when an old key-method is configured.\n\nReferences\n==========\n\nhttps://community.openvpn.net/openvpn/wiki/CVE-2017-12166\nhttps://github.com/OpenVPN/openvpn/commit/3b1a61e9fb27213c46f76312f4065816bee8ed01\nhttps://security.archlinux.org/CVE-2017-12166", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2017-09-28T00:00:00", "type": "archlinux", "title": "[ASA-201709-21] openvpn: arbitrary code execution", "bulletinFamily": "unix", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 6.8, "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2017-12166"], "modified": "2017-09-28T00:00:00", "id": "ASA-201709-21", "href": "https://security.archlinux.org/ASA-201709-21", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}], "fedora": [{"lastseen": "2020-12-21T08:17:54", "description": "OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single UDP or TCP port.
