Descriptions

strtod.c, as used in the zend_strtod function in PHP 5.2 before 5.2.17 and 5.3 before 5.3.5, and other products, allows context-dependent attackers to cause a denial of service (infinite loop) via a certain floating-point value in scientific notation, which is not properly handled in x87 FPU registers, as demonstrated using 2.2250738585072011e-308.

strtod.c, tal como se utiliza en la función zend_strtod en PHP v5.2 anterior de v5.2.17 y v5.3 anterior de v5.3.5, y otros productos, permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito) a través de un cierto valor de punto flotante en notación científica, que no se manipula correctamente en los registros FPU x87.
