CWE-119  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.2 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds 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.
