CVE-2014-8100: The Render extension in XFree86 4.0.1, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka...

Security readout for executives and security teams

This is an old X11 Render extension memory-safety issue. An authenticated remote user could crash the X server and may be able to run code through malformed Render requests. It matters mainly where legacy X.Org or XFree86 systems still accept remote authenticated X11 connections. Exposure is most likely on legacy Unix/Linux desktops, servers, appliances, or thin-client environments running old X.Org/XFree86 builds, especially where authenticated users can connect to an X server remotely. Modern systems with vendor backported fixes may not report version 1.16.3 but can still be patched. Treat this as a legacy exposure cleanup item with high priority where X11 is remotely accessible or shared by multiple users. It is less urgent for isolated, fully patched systems, but unsupported graphical stacks should be removed from production. Mitigation focus: Upgrade X.Org Server to 1.16.3 or a vendor-fixed backported package.; Apply Debian, Gentoo, Mageia, Oracle, or other relevant vendor security updates.; Restrict authenticated remote X11 access where it is not required..
