Scientific Linux Security Update : busybox on SL6.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

It was found that the mdev BusyBox utility could create certain
directories within /dev with world-writable permissions. A local
unprivileged user could use this flaw to manipulate portions of the
/dev directory tree. (CVE-2013-1813)

This update also fixes the following bugs :

- Previously, due to a too eager string size optimization
on the IBM System z architecture, the 'wc' BusyBox
command failed after processing standard input with the
following error :

wc: : No such file or directory

This bug was fixed by disabling the string size optimization and the
'wc' command works properly on IBM System z architectures.

- Prior to this update, the 'mknod' command was unable to
create device nodes with a major or minor number larger
than 255. Consequently, the kdump utility failed to
handle such a device. The underlying source code has
been modified, and it is now possible to use the 'mknod'
command to create device nodes with a major or minor
number larger than 255.

- If a network installation from an NFS server was
selected, the 'mount' command used the UDP protocol by
default. If only TCP mounts were supported by the
server, this led to a failure of the mount command. As a
result, Anaconda could not continue with the
installation. This bug is now fixed and NFS mount
operations default to the TCP protocol.
