"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting
    the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a
    denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE:
    this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability
    in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary
    hash function that is appropriate for the application. (CVE-2012-0039)

Note that Nessus relies on the presence of the package as reported by the vendor.");
