    - ------------------------------------------------------------------------- Debian Security Advisory DSA-4984-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso October 12, 2021 https://www.debian.org/security/faq

    Package : flatpak
    CVE ID : CVE-2021-41133
    Debian Bug : 995935

    It was discovered that sandbox restrictions in Flatpak, an application deployment framework for desktop apps, could be bypassed for a Flatpak
    app with direct access to AF_UNIX sockets, by manipulating the VFS using mount-related syscalls that are not blocked by Flatpak's denylist
    seccomp filter.

    Details can be found in the upstream advisory at https://github.com/flatpak/flatpak/security/advisories/GHSA-67h7-w3jq-vh4q

    For the stable distribution (bullseye), this problem has been fixed in
    version 1.10.5-0+deb11u1.

    We recommend that you upgrade your flatpak packages.

    For the detailed security status of flatpak please refer to its security tracker page at:
    https://security-tracker.debian.org/tracker/flatpak
