Enrico Weigelt, metux IT consult 601fd0fd84 xfixes/xace: fix pointer type mismatch on XFixesSelectSelectionInput() 
This could potentially be security related or crash the server:

XFixesSelectSelectionInput() calls the XACE_SELECTION_ACCESS hook with
wrong parameter type: XID instead of pointer to Selection struct.
It seems that it hadn't been kept up in XACE changed to polyinstantiation.

When XACE is used (eg. Security or SELinux extension enabled), this can
easily lead to memory corruptions at attacker-controlled locations, since
the client-given XID is interpreted as the memory location of Selection
structure.

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
