Descriptions

Multiple integer signedness errors in the pcf_get_encodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row.

Múltiples erroes de signo de enteros en la función pcf_get_encodings en pcf/pcfread.c en FreeType anterior a 2.5.4 permiten a atacantes remotos causar una denegación de servicio (desbordamiento de enteros, referencia a puntero nulo y caída de aplicación) a través de un fichero PCF manipulado que especifica valores negativos para la primera columna y la primera fila.
