Azure Linux 3.0 Security Update: python3 (CVE-2023-27043)

medium Nessus Plugin ID 216289

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of python3 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-27043 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 this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
