Fedora 43 : barman / python-uv-build / ruff / rust-archive-trait / etc (2026-fa66e0fef2)

high Nessus Plugin ID 375401

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-fa66e0fef2 advisory.

 Update `uv` and `python-uv-build` to [version 0.13.5](https://github.com/astral- sh/uv/blob/0.13.5/CHANGELOG.md). This includes some [breaking changes to `uv`](https://github.com/astral- sh/uv/blob/0.13.5/CHANGELOG.md#breaking-changes) (but none to `python-uv-build`); however, most users will not need to make any changes. The `uv` package has also been rebuilt with updated `rustls` and `webpki` dependencies, fixing RUSTSEC-2026-0346, RUSTSEC-2026-0347, RUSTSEC-2026-0348, RUSTSEC-2026-0349, RUSTSEC-2026-0381, RUSTSEC-2026-0383, and RUSTSEC-2026-0382. This includes fixes for the eMudhra intermediate CA compromise. Futhermore, `uv` 0.13.5 updates the latest managed CPython builds for 3.11 and newer to builds that distrust the eMudhra certificates. Finally, the system-wide configuration file (`uv.toml`) now sets `system-certs = true`, which means that, by default, the system-wide trust store is used instead of the root certificates bundled with `uv`. This better integrates with system-wide trust settings, and `uv` users can benefit from prompt security updates to the system-wide CA list.

 Update `ruff` to [version 0.17.2](https://github.com/astral-sh/ruff/blob/0.17.2/CHANGELOG.md) and `ty` to [version 0.0.91](https://github.com/astral-sh/ty/blob/0.0.91/CHANGELOG.md). Similarly, this includes some small [breaking changes](https://github.com/astral-sh/ruff/blob/0.17.2/CHANGELOG.md#breaking-changes).

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 packages.
