For builds of Xorg lacking -D_FORTIFY_SOURCE=2 (or 32-bit systems lacking the fix to fortify) this can lead to arbitrary code execution as the Xorg user, usually root. When built with fortify, this is a denial of service, since Xorg will abort. Proposed solution patch series can be found here: 1/4 http://patchwork.freedesktop.org/patch/10000/ 2/4 http://patchwork.freedesktop.org/patch/9998/ 3/4 http://patchwork.freedesktop.org/patch/9999/ 4/4 http://patchwork.freedesktop.org/patch/10001/ -Kees  http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=7c1f4834d398163d1ac8101e35e9c36fc3176e6e -- Kees Cook Chrome OS Security
