An update for flatpak is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1380 Final 1.0 1.0 2021-10-15 Initial 2021-10-15 2021-10-15 openEuler SA Tool V1.0 2021-10-15 flatpak security update An update for flatpak is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. flatpak is a system for building, distributing and running sandboxed desktop applications on Linux. See https://wiki.gnome.org/Projects/SandboxedApps for more information. Security Fix(es): Flatpak before 1.0.8, 1.1.x and 1.2.x before 1.2.4, and 1.3.x before 1.3.1 allows a sandbox bypass. Flatpak versions since 0.8.1 address CVE-2017-5226 by using a seccomp filter to prevent sandboxed apps from using the TIOCSTI ioctl, which could otherwise be used to inject commands into the controlling terminal so that they would be executed outside the sandbox after the sandboxed app exits. This fix was incomplete: on 64-bit platforms, the seccomp filter could be bypassed by an ioctl request number that has TIOCSTI in its 32 least significant bits and an arbitrary nonzero value in its 32 most significant bits, which the Linux kernel would treat as equivalent to TIOCSTI.(CVE-2019-10063) An update for flatpak is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high.
