Bastian Blank reported a denial of service vulnerability in Email::Address, a Perl module for RFC 2822 address parsing and creation. Email::Address::parse used significant time on parsing empty quoted strings. A remote attacker able to supply specifically crafted input to an application using Email::Address for parsing, could use this flaw to mount a denial of service attack against the application.
