CVE-2017-2625 (enterprise_linux, enterprise_linux_desktop, enterprise_linux_server, enterprise_linux_server_aus, enterprise_linux_server_eus, enterprise_linux_workstation, libxdmcp)

It was discovered that libXdmcp before 1.1.2 including used weak entropy to generate session keys. On a multi-user system using xdmcp, a local attacker could potentially use information available from the process list to brute force the key, allowing them to hijack other users’ sessions.
