Created: Mar 18, 2015    Updated: Dec 19, 2017
Resolved Date: Apr 3, 2015
Previous ID: LIN4-32361
Found In Version: 5.0.1.24
Fix Version: 5.0.1.25
Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Kernel

Description

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.
