"The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2023-87771f4249 advisory.
- 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)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
