"The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced
in the RHSA-2012:0102 advisory.

    Red Hat Network (RHN) Proxy provides a mechanism for caching content, such
    as package updates from Red Hat or custom content created for an
    organization on an internal, centrally-located server.

    If a user submitted a system registration XML-RPC call to an RHN Proxy
    server (for example, by running rhnreg_ks) and that call failed, their
    RHN user password was included in plain text in the error messages both
    stored in the server log and mailed to the server administrator. With this
    update, user passwords are excluded from these error messages to avoid the
    exposure of authentication credentials. (CVE-2012-0059)

    Users of Red Hat Network Proxy are advised to upgrade to these updated
    packages, which correct this issue. For this update to take effect,
    Red Hat Network Proxy must be restarted. Refer to the Solution section for
    details.

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

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