Descriptions

scanf.c in PHP 5.1.4 and earlier, and 4.4.3 and earlier, allows context-dependent attackers to execute arbitrary code via a sscanf PHP function call that performs argument swapping, which increments an index past the end of an array and triggers a buffer over-read.

scanf.c en PHP 5.1.4 y anteriores, y 4.4.3 y anteriores, permite a atacantes (locales o remotos dependiendo del contexto) ejecutar código de su elección mediante una llamada a la función sscanf de PHP que realiza un intercambio de argumentos que incrementa un índice más allá del final de un array y dispara una lectura de búfer fuera de límite.
