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 3.2之前版本在procfs实现中的fs/proc/root.c中存在漏洞，该漏洞源于未正确相互影响CLONE_NEWPID克隆系统调用。远程攻击者可利用该漏洞通过制造许多链接到后台程序，使用PID命名空间隔离客户导致拒绝服务（引用泄漏和内存消耗）。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
fs/proc/root.c in the procfs implementation in the Linux kernel before 3.2 does not properly interact with CLONE_NEWPID clone system calls, which allows remote attackers to cause a denial of service (reference leak and memory consumption) by making many connections to a daemon that uses PID namespaces to isolate clients, as demonstrated by vsftpd.
