Package        : libx11
CVE ID         : CVE-2021-31535
Debian Bug     : 988737

Roman Fiedler reported that missing length validation in various
functions provided by libx11, the X11 client-side library, allow
to inject X11 protocol commands on X clients, leading to
authentication bypass, denial of service or potentially the
execution of arbitrary code.

For the stable distribution (buster), this problem has been fixed in
version 2:1.6.7-1+deb10u2.

We recommend that you upgrade your libx11 packages.

For the detailed security status of libx11 please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/libx11
