    Package : sddm
    CVE ID : CVE-2020-28049
    Debian Bug : 973748

    Fabian Vogt discovered a flaw in sddm, a modern display manager for X11.
    A local attacker can take advantage of a race condition when creating
    the Xauthority file to escalate privileges.

    For the stable distribution (buster), this problem has been fixed in
    version 0.18.0-1+deb10u1.

    We recommend that you upgrade your sddm packages.

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