Jan-Niklas Sohn discovered two out of bound memory writes in X.Org Server’s ProcXkbSetGeometry and ProcXkbSetDeviceInfo Xkb extensions. These issues could be exploited by an attacker to cause denial of service, privilege escalation or arbitrary code execution.

For Debian 8 jessie, these problems have been fixed in version 2:1.16.4-1+deb8u7.

For Debian 9 stretch, these problems have been fixed in version 2:1.19.2-1+deb9u10.
