Título:	FreeBSD Security Advisory (FreeBSD-SA-04:03.jail.asc)
Resumen:	The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-04:03.jail.asc
Descripción:	Summary: The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-04:03.jail.asc Vulnerability Insight: The jail(2) system call allows a system administrator to lock up a process and all its descendants inside a closed environment with very limited ability to affect the system outside that environment, even for processes with superuser privileges. It is an extension of, but far more stringent than, the traditional Unix chroot(2) system call. The jail_attach(2) system call, which was introduced in FreeBSD 5 before 5.1-RELEASE, allows a non-jailed process to permanently move into an existing jail. A programming error has been found in the jail_attach(2) system call which affects the way that system call verifies the privilege level of the calling process. Instead of failing immediately if the calling process was already jailed, the jail_attach(2) system call would fail only after changing the calling process's root directory. Solution: Upgrade your system to the appropriate stable release or security branch dated after the correction date. CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
