    - ------------------------------------------------------------------------- Debian Security Advisory DSA-5055-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso January 24, 2022 https://www.debian.org/security/faq

    Package : util-linux
    CVE ID : CVE-2021-3995 CVE-2021-3996

    The Qualys Research Labs discovered two vulnerabilities in util-linux's libmount. These flaws allow an unprivileged user to unmount other users' filesystems that are either world-writable themselves or mounted in a world-writable directory (CVE-2021-3996), or to unmount FUSE filesystems
    that belong to certain other users (CVE-2021-3995).

    For the stable distribution (bullseye), these problems have been fixed in version 2.36.1-8+deb11u1.

    We recommend that you upgrade your util-linux packages.

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