Fedora 35 : python3.7 (2022-fdb2739feb)

high Nessus Plugin ID 169133

Language:

Synopsis

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

Description

The remote Fedora 35 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2022-fdb2739feb advisory.

 - An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
 For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)

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 python3.7 package.
