CVE-2014-9426
PHP Fileinfo Magic Memory Corruption Denial of Service
Description
The apprentice_load function in libmagic/apprentice.c in the Fileinfo component in PHP through 5.6.4 attempts to perform a free operation on a stack-based character array, which allows remote attackers to cause a denial of service (memory corruption or application crash) or possibly have unspecified other impact via unknown vectors. NOTE: this is disputed by the vendor because the standard erealloc behavior makes the free operation unreachable

Action Type Old Value New Value Removed Translation La función apprentice_load en libmagic/apprentice.c en el componente Fileinfo en PHP a través de 5.6.4 intenta realizar una operación libre en un array de caracteres basado en pila, lo que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria o caída de la aplicación) o la posibilidad de tener otro impacto sin especificar a través de vectores no conocidos. Added Translation ** DISPUTADA ** La función apprentice_load en libmagic/apprentice.c en el componente Fileinfo en PHP hasta 5.6.4 intenta realizar una operación libre sobre un array de caracteres basado en pila, lo que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria o caída de la aplicación) o posiblemente tener otro impacto no especificado a través de vectores desconocidos. NOTA: esto lo disputa el proveedor porque el comportamiento erealloc estándar hace que la operación libre sea inalcanzable. -
