Vulnerability Title

Vulnerability Description
The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary.

Vulnerability Title
Linux kernel fs/proc/array.c do_task_stat函数信息泄露漏洞
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。 Linux kernel 2.6.39-rc1之前版本的fs/proc/array.c中的do_task_stat函数不能执行预期的uid检查。本地用户可通过读取已执行PIE二进制进程的/proc/#####/stat文件中的start_code和end_code域击败ASLR保护机制。
