Descriptions

Multiple integer overflows in X.org libX11 1.5.99.901 (1.6 RC1) and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XQueryFont, (2) _XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5) XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8) XGetKeyboardMapping, (9) XGetWindowProperty, (10) XGetImage, (11) LoadColornameDB, (12) XrmGetFileDatabase, (13) _XimParseStringFile, or (14) TransFileName functions.

Múltiples desbordamientos de enteros en X.org libX11 v1.5.99.901 (1.6 RC1) y anteriores permiten que los servidores X provoquen una asignación de memoria insuficiente y un desbordamiento de búfer a través de vectores relacionados con las funciones (1) XQueryFont, (2) _XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5) XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8) XGetKeyboardMapping, (9) XGetWindowProperty, y (10) XGetImage.
