The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:1536 advisory.

    Libguestfs is a library and set of tools for accessing and modifying guest     disk images.

    It was found that guestfish, which enables shell scripting and command line     access to libguestfs, insecurely created the temporary directory used to     store the network socket when started in server mode. A local attacker     could use this flaw to intercept and modify other user's guestfish command,     allowing them to perform arbitrary guestfish actions with the privileges of     a different user, or use this flaw to obtain authentication credentials.
    (CVE-2013-4419)

    This issue was discovered by Michael Scherer of the Red Hat Regional IT     team.

    These updated libguestfs packages include numerous bug fixes and     enhancements. Space precludes documenting all of these changes in this     advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical     Notes, linked to in the References, for information on the most significant     of these changes.

    All libguestfs users are advised to upgrade to these updated packages,     which contain backported patches to correct these issues and add these     enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
