Versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4 contain a vulnerability similar to CVE-2017-5226, but using the `TIOCLINUX` ioctl command instead of `TIOCSTI`. If a Flatpak app is run on a Linux virtual console such as `/dev/tty1`, it can copy text from the virtual console and paste it into the command buffer, from which the command might be run after the Flatpak app has exited. Ordinary graphical terminal emulators like xterm, gnome-terminal and Konsole are unaffected. This vulnerability is specific to the Linux virtual consoles `/dev/tty1`, `/dev/tty2` and so on. A patch is available in versions 1.10.8, 1.12.8, 1.14.4, and 1.15.4. As a workaround, don't run Flatpak on a Linux virtual console. Flatpak is primarily designed to be used in a Wayland or X11 graphical environment.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-03-16 16:15:00","updated_at":"2023-12-23 10:15:00"},"problem_types":["NVD-CWE-noinfo"],"metrics":[],"references":[{"url":"https://github.com/flatpak/flatpak/commit/8e63de9a7d3124f91140fc74f8ca9ed73ed53be9","name":"https://github.com/flatpak/flatpak/commit/8e63de9a7d3124f91140fc74f8ca9ed73ed53be9","refsource":"MISC","tags":[],"title":"run: Prevent TIOCLINUX ioctl, the same as TIOCSTI · flatpak/flatpak@8e63de9 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://security.gentoo.org/glsa/202312-12","name":"https://security.gentoo.org/glsa/202312-12","refsource":"","tags":[],"title":"Flatpak: Multiple Vulnerabilities (GLSA 202312-12) — Gentoo security","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/flatpak/flatpak/security/advisories/GHSA-7qpw-3vjv-xrqp","name":"https://github.com/flatpak/flatpak/security/advisories/GHSA-7qpw-3vjv-xrqp","refsource":"MISC","tags":[],"title":"CVE-2023-28100: TIOCLINUX can send commands outside sandbox if running on a virtual console · Advisory · flatpak/flatpak · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://marc.info/?l=oss-security&m=167879021709955&w=2","name":"https://marc.info/?l=oss-security&m=167879021709955&w=2","refsource":"MISC","tags":[],"title":"'Re: [oss-security] TTY pushback vulnerabilities / TIOCSTI' - MARC","mime":"text/x-c","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-28100","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28100","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"28100","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"flatpak","cpe5":"flatpak","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2023-28100","qid":"161068","title":"Oracle Enterprise Linux Security Update for flatpak (ELSA-2023-6518)"},{"cve":"CVE-2023-28100","qid":"161150","title":"Oracle Enterprise Linux Security Update for flatpak (ELSA-2023-7038)"},{"cve":"CVE-2023-28100","qid":"181864","title":"Debian Security Update for flatpak (CVE-2023-28100)"},{"cve":"CVE-2023-28100","qid":"242294","title":"Red Hat Update for flatpak security (RHSA-2023:6518)"},{"cve":"CVE-2023-28100","qid":"242423","title":"Red Hat Update for flatpak security (RHSA-2023:7038)"},{"cve":"CVE-2023-28100","qid":"283814","title":"Fedora Security Update for flatpak (FEDORA-2023-b0717d8c45)"},{"cve":"CVE-2023-28100","qid":"283849","title":"Fedora Security Update for flatpak (FEDORA-2023-9fbc701e0d)"},{"cve":"CVE-2023-28100","qid":"284241","title":"Fedora Security Update for flatpak (FEDORA-2023-508e400dec)"},{"cve":"CVE-2023-28100","qid":"355585","title":"Amazon Linux Security Advisory for flatpak : ALAS2-2023-2134"},{"cve":"CVE-2023-28100","qid":"710812","title":"Gentoo Linux Flatpak Multiple Vulnerabilities (GLSA 202312-12)"},{"cve":"CVE-2023-28100","qid":"753858","title":"SUSE Enterprise Linux Security Update for flatpak (SUSE-SU-2023:1714-1)"},{"cve":"CVE-2023-28100","qid":"753859","title":"SUSE Enterprise Linux Security Update for flatpak (SUSE-SU-2023:1713-1)"},{"cve":"CVE-2023-28100","qid":"753883","title":"SUSE Enterprise Linux Security Update for flatpak (SUSE-SU-2023:1712-1)"},{"cve":"CVE-2023-28100","qid":"941369","title":"AlmaLinux Security Update for flatpak (ALSA-2023:6518)"},{"cve":"CVE-2023-28100","qid":"941429","title":"AlmaLinux Security Update for flatpak (ALSA-2023:7038)"}]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-28100","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux.
