{"id":"CVE-2020-13753","details":"The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226.","modified":"2026-04-16T04:37:07.824382610Z","published":"2020-07-14T14:15:17.603Z","related":["SUSE-SU-2020:1990-1","SUSE-SU-2020:1992-1","SUSE-SU-2020:2069-1","SUSE-SU-2022:0142-1","SUSE-SU-2022:0182-1","SUSE-SU-2022:0182-2","SUSE-SU-2022:0183-1","openSUSE-SU-2020:1064-1","openSUSE-SU-2022:0182-1","openSUSE-SU-2024:11506-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GER2ATKZXDHM7FFYJH67ZPNZZX5VOUVM/"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202007-11"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4422-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4724"},{"type":"ADVISORY","url":"https://www.openwall.com/lists/oss-security/2020/07/10/1"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00074.html"},{"type":"FIX","url":"https://trac.webkit.org/changeset/262368/webkit"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2.28.3"}]},{"events":[{"introduced":"0"},{"fixed":"2.28.3"}]},{"events":[{"introduced":"0"},{"last_affected":"31"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.10"}]},{"events":[{"introduced":"0"},{"last_affected":"20.04"}]},{"events":[{"introduced":"0"},{"last_affected":"15.1"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-13753.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
