{"id":"UBUNTU-CVE-2024-32462","details":"Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. in versions before 1.10.9, 1.12.9, 1.14.6, and 1.15.8, a malicious or compromised Flatpak app could execute arbitrary code outside its sandbox. Normally, the `--command` argument of `flatpak run` expects to be given a command to run in the specified Flatpak app, optionally along with some arguments. However it is possible to instead pass `bwrap` arguments to `--command=`, such as `--bind`. It's possible to pass an arbitrary `commandline` to the portal interface `org.freedesktop.portal.Background.RequestBackground` from within a Flatpak app. When this is converted into a `--command` and arguments, it achieves the same effect of passing arguments directly to `bwrap`, and thus can be used for a sandbox escape. The solution is to pass the `--` argument to `bwrap`, which makes it stop processing options. This has been supported since bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9, 1.12.9, and 1.14.6.","modified":"2026-09-10T16:30:18.809157018Z","published":"2024-04-18T18:15:00Z","upstream":["CVE-2024-32462"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-32462"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-32462"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2024/04/18/5"},{"type":"REPORT","url":"https://github.com/flatpak/flatpak/security/advisories/GHSA-phv6-cpc2-2fgj"},{"type":"REPORT","url":"https://github.com/flatpak/flatpak/commit/72016e3fce8fcbeab707daf4f1a02b931fcc004d"},{"type":"REPORT","url":"https://github.com/flatpak/flatpak/commit/81abe2a37d363f5099c3d0bdcd0caad6efc5bf97"},{"type":"REPORT","url":"https://github.com/flatpak/flatpak/commit/b7c1a558e58aaeb1d007d29529bbb270dc4ff11e"},{"type":"REPORT","url":"https://github.com/flatpak/flatpak/commit/bbab7ed1e672356d1a78b422462b210e8e875931"}],"affected":[{"package":{"name":"flatpak","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/flatpak?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.8.7-5","0.10.0-1","0.10.0-2","0.10.1-1","0.10.2-1","0.10.2.1-1","0.10.2.1-2","0.10.3-1","0.11.1-0ubuntu1","0.11.3-2","0.11.3-3","0.11.7-0ubuntu0.1","1.0.1-0ubuntu0.1","1.0.6-0ubuntu0.1","1.0.7-0ubuntu0.18.04.1","1.0.8-0ubuntu0.18.04.1","1.0.9-0ubuntu0.1","1.0.9-0ubuntu0.2","1.0.9-0ubuntu0.3","1.0.9-0ubuntu0.4","1.0.9-0ubuntu0.4+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"flatpak","binary_version":"1.0.9-0ubuntu0.4+esm1"},{"binary_version":"1.0.9-0ubuntu0.4+esm1","binary_name":"flatpak-tests"},{"binary_version":"1.0.9-0ubuntu0.4+esm1","binary_name":"gir1.2-flatpak-1.0"},{"binary_name":"libflatpak0","binary_version":"1.0.9-0ubuntu0.4+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32462.json"}},{"package":{"name":"flatpak","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/flatpak?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.3-1","1.6.0-1","1.6.1-1","1.6.2-1","1.6.3-1","1.6.5-0ubuntu0.1","1.6.5-0ubuntu0.2","1.6.5-0ubuntu0.3","1.6.5-0ubuntu0.4","1.6.5-0ubuntu0.5","1.6.5-0ubuntu0.5+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"flatpak","binary_version":"1.6.5-0ubuntu0.5+esm1"},{"binary_name":"flatpak-tests","binary_version":"1.6.5-0ubuntu0.5+esm1"},{"binary_name":"gir1.2-flatpak-1.0","binary_version":"1.6.5-0ubuntu0.5+esm1"},{"binary_version":"1.6.5-0ubuntu0.5+esm1","binary_name":"libflatpak0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32462.json"}},{"package":{"name":"flatpak","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/flatpak?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.2-3","1.12.2-1","1.12.2-2","1.12.3-1","1.12.4-1","1.12.5-1","1.12.6-1","1.12.7-1","1.12.7-1ubuntu0.1","1.12.7-1ubuntu0.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"flatpak","binary_version":"1.12.7-1ubuntu0.1+esm1"},{"binary_name":"flatpak-tests","binary_version":"1.12.7-1ubuntu0.1+esm1"},{"binary_version":"1.12.7-1ubuntu0.1+esm1","binary_name":"gir1.2-flatpak-1.0"},{"binary_name":"libflatpak0","binary_version":"1.12.7-1ubuntu0.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32462.json"}},{"package":{"name":"flatpak","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/flatpak?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.14.6-1"}]}],"versions":["1.14.4-2","1.14.5-1","1.14.5-1build1","1.14.5-1build4","1.14.5-1build5","1.14.5-1build6"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"flatpak","binary_version":"1.14.6-1"},{"binary_name":"flatpak-tests","binary_version":"1.14.6-1"},{"binary_name":"gir1.2-flatpak-1.0","binary_version":"1.14.6-1"},{"binary_version":"1.14.6-1","binary_name":"libflatpak0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32462.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
