This update for xorg-x11-server provides the following fixes :
CVE-2017-10971: Fix endianess handling of GenericEvent to prevent a stack overflow by clients. (bnc#1035283)
Make sure the type of all events to be sent by ProcXSendExtensionEvent are in the allowed range.
CVE-2017-10972: Initialize the xEvent eventT with zeros to avoid information leakage.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
