The remote MiracleLinux 4 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2014-023:01 advisory.

    Busybox is a single binary which includes versions of a large number of system commands, including a     shell. This package can be very useful for recovering from certain types of system failures, particularly     those involving broken shared libraries.
    Security issues fixed with this release:
     CVE-2013-1813     util-linux/mdev.c in BusyBox before 1.21.0 uses 0777 permissions for parent directories when creating     nested directories under /dev/, which allows local users to have unknown impact and attack vectors.
    Fixed bugs:
     Previously, the wc BusyBox command failed after processing standard input with the following error: wc:
    : No such file or directory. This has been fixed by disabling the string size optimization      The mknod command can now creates device nodes with a major or minor number larger than 255.
     When installing from an NFS server, the mount command could fail if the NFS server only supported TCP     mounts, and the installation could not continue. This has been fixed and NFS mounts now default to TCP.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

Updated busybox packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

All busybox users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
