Description Andrej Nemec 2017-05-18 08:48:27 UTC 
perltidy relies on the current working directory for certain output files and does not have a symlink-attack protection mechanism, which allows local users to overwrite arbitrary files by creating a symlink, as demonstrated by creating a perltidy.ERR symlink that the victim cannot delete.
