Renamed copy of xorg-server-1.17.0.ebuild works. http://lists.freedesktop.org/archives/xorg/2015-February/057158.html X.Org Security Advisory: Feb 10, 2015 - CVE-2015-0255 Information leak in the XkbSetGeometry request of X servers =========================================================== Description: ============ Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request. The issue stems from the server trusting the client to send valid string lengths in the request data. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. The data length is at least up to 64k, it is possible to obtain more data by chaining strings, each string length is then determined by whatever happens to be in that 16-bit region of memory. A similarly crafted request can likely cause the X server to crash. This issue has been assigned CVE-2015-0255 Affected Versions: ================== This bug appears to have been introduced in X11R6.1 (March 1996) and is thus believed to be present in every X server release since, including the current stable releases 1.16.3 and 1.17.0 Fixes: ====== A fix is available via the patch linked below which is intended to be included in xorg-server-1.16.4 and 1.17.1 http://cgit.freedesktop.org/xorg/xserver/commit/?id=20079c36cf7d377938ca5478447d8b9045cb7d43 Note that this patch requires another patch to apply without conflicts: http://cgit.freedesktop.org/xorg/xserver/commit/?id=81c90dc8f0aae3b65730409b1b615b5fa7280ebd
