{"id":"UBUNTU-CVE-2021-32563","details":"An issue was discovered in Thunar before 4.16.7 and 4.17.x before 4.17.2. When called with a regular file as a command-line argument, it delegates to a different program (based on the file type) without user confirmation. This could be used to achieve code execution.","modified":"2026-04-22T12:54:01.403544Z","published":"2021-05-11T05:15:00Z","upstream":["CVE-2021-32563"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-32563"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2021/05/09/2"},{"type":"REPORT","url":"https://gitlab.xfce.org/xfce/thunar/-/tags"},{"type":"REPORT","url":"https://gitlab.xfce.org/xfce/thunar/-/commit/9165a61f95e43cc0b5abf9b98eee2818a0191e0b"},{"type":"REPORT","url":"https://gitlab.xfce.org/xfce/thunar/-/commit/3b54d9d7dbd7fd16235e2141c43a7f18718f5664"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2021/05/11/3"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-32563"}],"affected":[{"package":{"name":"thunar","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/thunar@1.6.11-0ubuntu0.16.04.2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.10-1","1.6.10-2","1.6.10-2ubuntu1","1.6.11-0ubuntu0.16.04.1","1.6.11-0ubuntu0.16.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libthunarx-2-0","binary_version":"1.6.11-0ubuntu0.16.04.2"},{"binary_name":"thunar","binary_version":"1.6.11-0ubuntu0.16.04.2"},{"binary_version":"1.6.11-0ubuntu0.16.04.2","binary_name":"thunar-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-32563.json"}},{"package":{"name":"thunar","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/thunar@1.6.15-0ubuntu1.18.04.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.12-1","1.6.13-1","1.6.13-2","1.6.14-1","1.6.14-1ubuntu1","1.6.15-0ubuntu1","1.6.15-0ubuntu1.18.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libthunarx-2-0","binary_version":"1.6.15-0ubuntu1.18.04.1"},{"binary_name":"thunar","binary_version":"1.6.15-0ubuntu1.18.04.1"},{"binary_name":"thunar-data","binary_version":"1.6.15-0ubuntu1.18.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-32563.json"}},{"package":{"name":"thunar","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/thunar@1.8.14-0ubuntu1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.9-1","1.8.11-1","1.8.12-1","1.8.14-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"libthunarx-3-0","binary_version":"1.8.14-0ubuntu1"},{"binary_name":"thunar","binary_version":"1.8.14-0ubuntu1"},{"binary_name":"thunar-data","binary_version":"1.8.14-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-32563.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
