The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python.</p> <p><strong>Affected:</strong> Ubuntu:Pro:14.04:LTS: python2.7, Ubuntu:Pro:14.04:LTS: python3.5, Ubuntu:Pro:14.04:LTS: python3.4, Ubuntu:Pro:16.04:LTS: python2.7, Ubuntu:Pro:16.04:LTS: python3.5, Ubuntu:Pro:18.04:LTS: python2.7, Ubuntu:Pro:18.04:LTS: python3.6, Ubuntu:Pro:18.04:LTS: python3.7, Ubuntu:Pro:18.04:LTS: python3.8, Ubuntu:20.04:LTS: python3.8 and 6 more</p> <p>The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character.
