Synopsis

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

Description

The remote Fedora 43 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2026-72a7879d08 advisory.

 Update `python-urllib3` to [version 2.8.0](https://github.com/urllib3/urllib3/blob/2.8.0/CHANGES.rst), fixing three security issues:

 - The TLS configuration for HTTPS proxies could be ignored or overridden. (Rated high severity by upstream, [GHSA-8988-9cw3-xx77](https://github.com/urllib3/urllib3/security/advisories/GHSA-8988-9cw3-xx77))
 - `HTTPResponse.stream()` and `read_chunked()` could buffer a chunk-size line of unbounded length in memory. (Rated high severity by upstream, [GHSA- vxq7-64xx-v4gw](https://github.com/urllib3/urllib3/security/advisories/GHSA-vxq7-64xx-v4gw))
 - Chunked Deflate streaming could enter an infinite loop. (Rated medium severity by upstream, [GHSA- gh4c-6fx4-qh6g](https://github.com/urllib3/urllib3/security/advisories/GHSA-gh4c-6fx4-qh6g))

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

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-streamlink and / or python-urllib3 packages.
