    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
