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.
