Fedora 40 : python-dns (2024-930af3332f)

medium Nessus Plugin ID 194933

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 40 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2024-930af3332f 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.

Solution

Update the affected python-dns package.
