The Core X11 clients packages provide the xorg-x11-utils, xorg-x11-server-utils, and xorg-x11-apps clients that ship with the X Window System. It was found that the x11perfcomp utility included the current working directory in its PATH environment variable. Running x11perfcomp in an attacker-controlled directory would cause arbitrary code execution with the privileges of the user running x11perfcomp. Also with this update, the xorg-x11-utils and xorg-x11-server-utils packages have been upgraded to upstream version 7.5, and the xorg-x11-apps package to upstream version 7.6, which provides a number of bug fixes and enhancements over the previous versions. All users of xorg-x11-utils, xorg-x11-server-utils, and xorg-x11-apps are advised to upgrade to these updated packages, which fix these issues and add these enhancements.
