{"id":"ALPINE-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":"2026-11-03T06:32:23.728928414Z","published":"2020-07-14T14:15:17.603Z","upstream":["CVE-2020-13753"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-13753"}],"affected":[{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}},{"package":{"name":"webkit2gtk","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/webkit2gtk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13753.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
