ls in the fileutils or coreutils packages allows local users to consume a large amount of memory via a large -w value, which can be remotely exploited via applications that use ls, such as wu-ftpd.

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.
