The pserver_shutdown function in fence_egenera in cman 2.20080629 and 2.20080801 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/eglog temporary file.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
