MEDIUM

Linux Kernel < 3.17 - Denial of Service via pivot_root Chroot Directory Handling

Title source: llm
STIX 2.1

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.
