Descriptions

The stack randomization feature in the Linux kernel before 3.19.1 on 64-bit platforms uses incorrect data types for the results of bitwise left-shift operations, which makes it easier for attackers to bypass the ASLR protection mechanism by predicting the address of the top of the stack, related to the randomize_stack_top function in fs/binfmt_elf.c and the stack_maxrandom_size function in arch/x86/mm/mmap.c.

La característica de aleatoriedad de la pila en el Kernel de Linux anterior a 3.19.1 en plataformas de 64-bits utiliza un tipo de datos incorrecto por el resultado de operaciones de bitwise left-shift, lo que hace que sea más fácil para atacantes evadir el mecanismo de protección ASLR prediciendo direcciones del tope de la pila, relacionado con la función andomize_stack_top en fs/binfmt_elf.c y la función stack_maxrandom_size en arch/x86/mm/mmap.c.

An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four.
