"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2012:0436 advisory.

    Red Hat Network (RHN) Satellite is a systems management tool for
    Linux-based infrastructures. It allows for provisioning, monitoring, and
    remote management of multiple Linux deployments with a single, centralized
    tool.

    It was found that a remote attacker could upload packages to an RHN
    Satellite server's NULL organization without any authorization or
    authentication. (The NULL organization stores packages synced from RHN
    Hosted.) Although an attacker cannot put packages into an arbitrary channel
    and have client systems download them, they could use the flaw to consume
    all the free space in the partition (/var/) used to store synced packages.
    With no free space, Satellite would be unable to download updates and new
    packages, preventing client systems from obtaining them. (CVE-2012-1145)

    All users of Red Hat Network Satellite are advised to upgrade to these
    updated packages, which correct this issue. For this update to take effect,
    Red Hat Network Satellite 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.");
