Problem Description\r\n\r\n chroot&#40;&#41; is a system call that is often used to provide an\r\n additional layer of security when untrusted programs are\r\n run. The call to chroot&#40;&#41; is normally used to ensure that\r\n code run after it can only access files at or below a given\r\n directory. \r\n\r\n Originally, chroot&#40;&#41; was used to test systems software in \r\n a safe environment. It is now generally used to lock users \r\n into an area of the file system so that they can not look \r\n at or affect the important parts of the system they are on. \r\n \r\n Several programs use chroot jails to ensure that even if \r\n you break into the process&#39;s address space, you can&#39;t do \r\n anything harmful to the whole system. If chroot&#40;&#41; can be \r\n broken then this precaution is broken. \r\n\r\n A known exploit can break a chroot prison.\r\n\r\n The Common Vulnerabilities and Exposures project \r\n &#40;cve.mitre.org&#41; has assigned the name CAN-2004-1124 to t\r\n his issue.\r\n\r\n A new file system tunable, CHROOT_SECURITY is provided to\r\n protect against the known exploit for escaping from a chroot\r\n prison. The new tunable is described in /etc/conf/dtune.d/fs\r\n and defined in /etc/conf/mtune.d/fs. Protection is provided\r\n by the default value of 1 but traditional behavior may be\r\n obtained by resetting CHROOT_SECURITY to 0. \r\n\r\n chroot&#40;&#41; is a good way to increase the security of the\r\n software provided that secure programming guidelines are \r\n utilized and chroot&#40;&#41; system call limitations are taken \r\n into account. Chrooting will prevent an attacker from \r\n reading files outside the chroot jail and will prevent \r\n many local UNIX attacks &#40;such as SUID abuse and /tmp \r\n race conditions&#41;.\r\n\r\n The number of ways that root user can break out of chroot \r\n is huge. If there is no root user defined within the \r\n chroot environment, no SUID binaries, no devices, and \r\n the daemon itself dropped root privileges right after \r\n calling chroot&#40;&#41; call breaking out of chroot appears to \r\n be impossible.\r\n\r\n2.
