    Debian Bug     : 968986
    
    Several vulnerabilities have been discovered in the X.Org X server.
    Missing input sanitising in X server extensions may result in local
    privilege escalation if the X server is configured to run with root
    privileges. In addition an ASLR bypass was fixed.
    
    For the stable distribution (buster), these problems have been fixed in
    version 2:1.20.4-1+deb10u1.
    
    We recommend that you upgrade your xorg-server packages.
    
    For the detailed security status of xorg-server please refer to its
    security tracker page at:
