NVD Description

Note: Versions mentioned in the description apply only to the upstream python39:3.9/python39-cryptography package and not the python39:3.9/python39-cryptography package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. 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.
