CVE-2014-7970

MEDIUM

Novell Suse Linux Enterprise Server < 3.17 - Denial of Service

Title source: rule

Description

The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.
