Descriptions

The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server.

La función do_anonymous_page en mm/memory.c en el kernel de Linux anterior v2.6.27.52, v2.6.32.x anterior v2.6.32.19, v2.6.34.x anterior v2.6.34.4, y v2.6.35.x anterior v2.6.35.2 no separa adecuadamente la pila y la cabecera, lo que permite a atacantes dependientes del contexto ejecutar código de su elección por escritura en el final de la página de un segmento de memoria compartida, como quedó demostrado con un ataque de memoria exhaustiva contra el servidor X.Org X.
