Package        : xorg-server
CVE ID         : CVE-2020-14345 CVE-2020-14346 CVE-2020-14347 CVE-2020-14361
                 CVE-2020-14362
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:
