Vulnerability Title
N/A
Vulnerability 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.

Linux kernel 权限许可和访问控制问题漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 基于64-bit平台的Linux kernel 3.18.9及之前版本的stack randomization功能存在安全漏洞，该漏洞源于bitwise left-shift操作的结果中存在不正确的数据类型。攻击者可通过预测栈顶地址利用该漏洞绕过ASLR保护机制。
