"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."
