The getSkillname function in the eve module in Conky 1.8.1 and earlier allows local users to overwrite arbitrary files via a symlink attack on /tmp/.cesf.
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.
