+----------------+
Fri Oct 6 09:08:21 EDT 2017
x-base/xorg-server rebuilt (build 4) to fix two vulnerabilities: CVE-2017-13721,
	which allowed an attacker to crash the X server or overwrite another
	client's data via a failure to validate shmseg resource ids, and
	CVE-2017-13723, which fixed a bug where xkb would use a single, static
	buffer to do all of its formatting, which has the potential to be
	exploitable in a whole multitude of ways. For more information see:
