Amazon Linux 2 Security Advisory: ALAS-2024-2687
Advisory Release Date: 2024-10-24 23:54 Pacific
Advisory Updated Date: 2024-10-31 18:00 Pacific
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. (CVE-2023-27043)
Affected Packages:
python3
