Title:	FreeBSD Security Advisory (FreeBSD-SA-08:08.nmount.asc)
Summary:	The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-08:08.nmount.asc
Description:	Summary: The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-08:08.nmount.asc Vulnerability Insight: The mount(2) and nmount(2) system calls are used by various utilities in the base system to graft a file system object on to the file system tree to a given mount point. It is possible to allow unprivileged users to utililize these system calls by setting the vfs.usermount sysctl(8) variable. Various user defined input such as mount points, devices, and mount options are prepared and passed as arguments to nmount(2) into the kernel. Under certain error conditions, user defined data will be copied into a stack allocated buffer stored in the kernel without sufficient bounds checking. Solution: Upgrade your system to the appropriate stable release or security branch dated after the correction date. CVSS Score: 6.9 CVSS Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
