Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (\u003eLP_NO) 'lp=none' arguments to the command line.","modified":"2026-03-12T22:30:29.459211Z","published":"2017-07-17T13:18:18.593Z","related":["MGASA-2017-0186","MGASA-2017-0187","MGASA-2017-0188","SUSE-SU-2017:2342-1","SUSE-SU-2017:2389-1","SUSE-SU-2017:2525-1","SUSE-SU-2017:2908-1","SUSE-SU-2017:2920-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/98651"},{"type":"ADVISORY","url":"https://alephsecurity.com/vulns/aleph-2017023"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3945"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"2.6.12"},{"fixed":"3.2.91"}]},{"events":[{"introduced":"3.3"},{"fixed":"3.10.106"}]},{"events":[{"introduced":"3.11"},{"fixed":"3.16.46"}]},{"events":[{"introduced":"3.17"},{"fixed":"3.18.55"}]},{"events":[{"introduced":"3.19"},{"fixed":"4.1.41"}]},{"events":[{"introduced":"4.2"},{"fixed":"4.4.70"}]},{"events":[{"introduced":"4.5"},{"fixed":"4.9.30"}]},{"events":[{"introduced":"4.10"},{"fixed":"4.11.3"}]},{"events":[{"introduced":"0"},{"last_affected":"4.12-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-1000363.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
