Descriptions

In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server.

En la función pcfGetProperties en bitmap/pcfread.c en libXfont, en versiones hasta la 1.5.2 y versiones 2.x hasta la 2.0.2, atacantes autenticados en un servidor X podrían utilizar la falta de una comprobación de límites (para archivos PCF) para llevar a cabo una sobrelectura de búfer con el fin de conseguir que se produzca una revelación de información o un cierre inesperado del servidor X.
