Description

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.

• x.org libxdmcp (< 1.1.2) • redhat enterprise linux 7.0 • redhat enterprise linux desktop 7.0 • redhat enterprise linux server 7.0 • redhat enterprise linux server aus 7.4 • redhat enterprise linux server eus 7.4 • redhat enterprise linux server eus 7.5 • redhat enterprise linux workstation 7.0
