CVE-2013-1858 in Linux Kernel

Resumen (Inglés)

The clone system-call implementation in the Linux kernel before 3.8.3 does not properly handle a combination of the CLONE_NEWUSER and CLONE_FS flags, which allows local users to gain privileges by calling chroot and leveraging the sharing of the / directory between a parent process and a child process.
