"The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2009-1341 advisory.

  - The (1) fence_apc and (2) fence_apc_snmp programs, as used in (a) fence 2.02.00-r1 and possibly (b) cman,
    when running in verbose mode, allows local users to append to arbitrary files via a symlink attack on the
    apclog temporary file. (CVE-2008-4579)

  - Red Hat Cluster Project 2.x allows local users to modify or overwrite arbitrary files via symlink attacks
    on files in /tmp, involving unspecified components in Resource Group Manager (aka rgmanager) before
    2.03.09-1, gfs2-utils before 2.03.09-1, and CMAN - The Cluster Manager before 2.03.09-1 on Fedora 9.
