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:
