    Package : firejail
    CVE ID : CVE-2021-26910

    Roman Fiedler discovered a vulnerability in the OverlayFS code in
    firejail, a sandbox program to restrict the running environment of
    untrusted applications, which could result in root privilege escalation.
    This update disables OverlayFS support in firejail.

    For the stable distribution (buster), this problem has been fixed in
    version 0.9.58.2-2+deb10u2.

    We recommend that you upgrade your firejail packages.

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