CVE-2002-0435: Race Condition
First published: Fri Jul 26 2002(Updated: )
Race condition in the recursive (1) directory deletion and (2) directory move in GNU File Utilities (fileutils) 4.1 and earlier allows local users to delete directories as the user running fileutils by moving a low-level directory to a higher level as it is being deleted, which causes fileutils to chdir to a ".." directory that is higher than expected, possibly up to the root file system.
