They can do this by manipulating the VFS using recent mount-related syscalls that are not blocked by Flatpak\u0026apos;s denylist seccomp filter, in order to substitute a crafted `/.flatpak-info` or make that file disappear entirely. Flatpak apps that act as clients for AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can escalate the privileges that the corresponding services will believe the Flatpak app has. Note that protocols that operate entirely over the D-Bus session bus (user bus), system bus or accessibility bus are not affected by this. This is due to the use of a proxy process `xdg-dbus-proxy`, whose VFS cannot be manipulated by the Flatpak app, when interacting with these buses. Patches exist for versions 1.10.4 and 1.12.0, and as of time of publication, a patch for version 1.8.2 is being planned. There are no workarounds aside from upgrading to a patched version.(CVE-2021-41133)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP1","name":"flatpak","purl":"pkg:rpm/openEuler/flatpak\u0026distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.3-7.oe1"}]}],"ecosystem_specific":{"aarch64":["flatpak-debuginfo-1.0.3-7.oe1.aarch64.rpm","flatpak-1.0.3-7.oe1.aarch64.rpm","flatpak-devel-1.0.3-7.oe1.aarch64.rpm","flatpak-debugsource-1.0.3-7.oe1.aarch64.rpm"],"noarch":["flatpak-help-1.0.3-7.oe1.noarch.rpm"],"src":["flatpak-1.0.3-7.oe1.src.rpm"],"x86_64":["flatpak-devel-1.0.3-7.oe1.x86_64.rpm","flatpak-1.0.3-7.oe1.x86_64.rpm","flatpak-debugsource-1.0.3-7.oe1.x86_64.rpm","flatpak-debuginfo-1.0.3-7.oe1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP2","name":"flatpak","purl":"pkg:rpm/openEuler/flatpak\u0026distro=openEuler-20.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.3-7.oe1"}]}],"ecosystem_specific":{"aarch64":["flatpak-debuginfo-1.0.3-7.oe1.aarch64.rpm","flatpak-1.0.3-7.oe1.aarch64.rpm","flatpak-devel-1.0.3-7.oe1.aarch64.rpm","flatpak-debugsource-1.0.3-7.oe1.aarch64.rpm"],"noarch":["flatpak-help-1.0.3-7.oe1.noarch.rpm"],"src":["flatpak-1.0.3-7.oe1.src.rpm"],"x86_64":["flatpak-devel-1.0.3-7.oe1.x86_64.rpm","flatpak-1.0.3-7.oe1.x86_64.rpm","flatpak-debugsource-1.0.3-7.oe1.x86_64.rpm","flatpak-debuginfo-1.0.3-7.oe1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2021-1404"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-41133"}],"database_specific":{"severity":"High"}}
