USN-875-1: Red Hat Cluster Suite vulnerabilities

18 December 2009

Red Hat Cluster Suite vulnerabilities



Multiple insecure temporary file handling vulnerabilities were discovered
in Red Hat Cluster. A local attacker could exploit these to overwrite
arbitrary local files via symlinks. (CVE-2008-4192, CVE-2008-4579,
CVE-2008-4580, CVE-2008-6552)

It was discovered that CMAN did not properly handle malformed configuration
files. An attacker could cause a denial of service (via CPU consumption and
memory corruption) in a node if the attacker were able to modify the
cluster configuration for the node. (CVE-2008-6560)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.10
Ubuntu 8.04
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
