Debian Security Advisory DSA-4758-1 [email protected]

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:
https://security-tracker.debian.org/tracker/xorg-server
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
