Moderate: python3 security update (Amazon Linux 2)

Published Oct 24, 2024 · Updated Oct 31, 2024

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2023-27043: 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.
