{"id":"CVE-2019-12210","details":"In Yubico pam-u2f 1.0.7, when configured with debug and a custom debug log file is set using debug_file, that file descriptor is not closed when a new process is spawned. This leads to the file descriptor being inherited into the child process; the child process can then read from and write to it. This can leak sensitive information and also, if written to, be used to fill the disk or plant misinformation.","modified":"2026-05-28T04:05:02.259617680Z","published":"2019-06-04T21:29:00.827Z","related":["SUSE-SU-2019:1749-1","SUSE-SU-2019:1750-1","openSUSE-SU-2019:1708-1","openSUSE-SU-2019:1725-1","openSUSE-SU-2024:11145-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:a:yubico:pam-u2f:1.0.7:*:*:*:*:*:*:*"],"vendor_product":"yubico:pam-u2f","source":"CPE_STRING","extracted_events":[{"last_affected":"1.0.7"}]}]},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00012.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00018.html"},{"type":"ADVISORY","url":"https://developers.yubico.com/pam-u2f/Release_Notes.html"},{"type":"FIX","url":"https://github.com/Yubico/pam-u2f/commit/18b1914e32b74ff52000f10e97067e841e5fff62"},{"type":"EVIDENCE","url":"http://www.openwall.com/lists/oss-security/2019/06/05/1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/yubico/pam-u2f","events":[{"introduced":"0"},{"fixed":"18b1914e32b74ff52000f10e97067e841e5fff62"}],"database_specific":{"source":"REFERENCES"}}],"versions":["pam_u2f-1.0.7","pam_u2f-1.0.6","pam_u2f-1.0.5","pam_u2f-1.0.4","pam_u2f-1.0.3","pam_u2f-1.0.2","pam_u2f-1.0.1","pam_u2f-1.0.0","pam_u2f-0.0.1","pam_u2f-0.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-12210.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
