Description

GNU contains a flaw that is triggered when parsing directories. The issue is due to a 'find' command initially caching directory contents. As the find searches each directory, changes in a cached directory that have not been searched yet will allow an attacker to inject a symlink. When find gets to the symlink, it will follow it and act on the newly specified target, even when find would otherwise ignore symlinks.
