Description Andrej Nemec 2018-06-20 10:35:18 EDT

The parse() method in the Email::Address module through 1.909 for Perl can consume a large amount of resources on specially prepared input, leading to Denial of Service. Prepared special input that caused this problem contained 30 form-field characters ("\f").
