RedHat Security Advisory RHSA-2009:1341

The remote host is missing updates announced in advisory RHSA-2009:1341. The Cluster Manager (cman) utility provides services for managing a Linux cluster. Multiple insecure temporary file use flaws were found in fence_apc_snmp and ccs_tool. A local attacker could use these flaws to overwrite an arbitrary file writable by a victim running those utilities (typically root) with the output of the utilities via a symbolic link attack. (CVE-2008-4579, CVE-2008-6552) Users of cman are advised to upgrade to these updated packages, which resolve these issues.
