X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, does not check the return values for setuid and seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail, such as by exceeding a ulimit. X.Org y XFree86, incluyendo libX11, xdm, xf86dga, xinit, xload, xtrans, y xterm, no comprueban los valores de retorno de las llamadas a setuid y seteuid al intentar eliminar privilegios, lo cual permite a usuarios locales obtener privilegios haciendo fallar estas llamadas, como por ejemplo excediendo un ulimit. • http://lists.freedesktop.org/archives/xorg/2006-June/016146.html http://mail.gnome.org/archives/beast/2006-December/msg00025.html http://secunia.com/advisories/21650 http://secunia.com/advisories/21660 http://secunia.com/advisories/21693 http://secunia.com/advisories/22332 http://secunia.com/advisories/25032 http://secunia.com/advisories/25059 http://security.gentoo.org/glsa/glsa-200608-25.xml http://security.gentoo.org/glsa/glsa-200704-22.xml http://www.debian.org/securit •
