Descriptions

The mem_write function in the Linux kernel before 3.2.2, when ASLR is disabled, does not properly check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by modifying process memory, as demonstrated by Mempodipper.

La función mem_write en el kernel de Linux anterior a versión 3.2.2, cuando ASLR está deshabilitado, no comprueba apropiadamente los permisos al escribir en /proc/(pid)/mem, lo que permite a los usuarios locales alcanzar privilegios al modificar la memoria del proceso, como es demostrado por Mempodipper .
