Descriptions

Multiple integer overflows in the (1) fs_get_reply, (2) fs_alloc_glyphs, and (3) fs_read_extent_info functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs reply, which triggers a buffer overflow.

Múltiples desbordamientos de enteros en las funciones (1) fs_get_reply, (2) fs_alloc_glyphs y (3) fs_read_extent_info en X.Org libXfont anterior a 1.4.8 y 1.4.9x anterior a 1.4.99.901 permiten a servidores remotos de fuentes ejecutar código arbitrario a través de una respuesta xfs manipulada, lo que provoca un desbordamiento de buffer.

Multiple out-of-bounds write flaws were found in the way libXfont parsed replies received from an X.org font server. A malicious X.org server could cause an X client to crash or, possibly, execute arbitrary code with the privileges of the X.Org server.
