Description

perltidy through 20160302, as used by perlcritic, check-all-the-things, and other software, 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.

Weakness classification

  • CWE-59: Improper Link Resolution Before File Access ('Link Following')
