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

Algorithmic complexity vulnerability in Address.pm in the Email-Address module 1.908 and earlier for Perl allows remote attackers to cause a denial of service (CPU consumption) via a crafted string containing a list of e-mail addresses in conjunction with parenthesis characters that can be associated with nested comments. NOTE: the default configuration in 1.908 mitigates this vulnerability but misparses certain realistic comments.

Algorithmic complexity vulnerability in Email::Address::List before 0.02, as used in RT 4.2.0 through 4.2.2, allows remote attackers to cause a denial of service (CPU consumption) via a string without an address.

Email::Address module before 1.904 for Perl uses an inefficient regular expression, which allows remote attackers to cause a denial of service (CPU consumption) via vectors related to "backtracking into the phrase," a different vulnerability than CVE-2014-0477.

The parse function in Email::Address module before 1.905 for Perl uses an inefficient regular expression, which allows remote attackers to cause a denial of service (CPU consumption) via an empty quoted string in an RFC 2822 address.
