The remote CentOS Linux 8 host has a package installed that is affected by a vulnerability as referenced in the CESA-2024:3275 advisory.

  - eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS     name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a     TuDoor attack. In other words, dnspython does not have the preferred behavior in which the DNS name     resolution algorithm would proceed, within the full time window, in order to wait for a valid packet.
    NOTE: dnspython 2.6.0 is unusable for a different reason that was addressed in 2.6.1. (CVE-2023-29483)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 8 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2024-3275 advisory.

    [1.15.0-12]
    - Security fix for CVE-2023-29483     Resolves: RHEL-32630

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of dnspython installed on the remote host is prior to 2.6.0rc1. It is, therefore, affected by a denial of service (DoS) vulnerability. The dnspython stub resolver is vulnerable to a potential DoS if a bad-in-some-way response from the right address and port forged by an attacker arrives before a legitimate one on the UDP port dnspython is using for that query. In this situation, dnspython might switch to querying another resolver or give up entirely, possibly denying service for that resolution.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. Also note that this plugin does not distinguish between Python packages installed via the OS package manager, Python packages installed via PIP, or other sources. As a result, packages provided by your OS package repository may have backported fixes that this plugin may incorrectly report as vulnerable. Please refer to the OS-specific plugins for CVE-2023-29483 to check for backported fixes.
