"The remote Fedora 44 host has packages installed that are affected by a vulnerability as referenced in the
FEDORA-2026-b8b59dcf44 advisory.

    Update `uv` and `python-uv-build` to [0.11.2](https://github.com/astral-sh/uv/blob/0.11.2/CHANGELOG.md).
    Version 0.11 includes changes to the networking stack used by `uv`. While its developers think that
    breakage will be rare, it is possible that these changes will result in the rejection of certificates
    previously trusted by `uv` so, they have marked the change as breaking out of an abundance of caution. The
    changes are largely driven by the upgrade of `reqwest`, which powers `uv`'s HTTP clients, to v0.13, which
    included some breaking changes to TLS certificate verification. This update also includes updates for
    several of `uv`s Rust library dependencies.

    ----

    Update `rust-openssl-probe` to [0.2.1](https://github.com/rustls/openssl-probe/releases/tag/0.2.1),
    including breaking changes introduced in [0.2.0](https://github.com/rustls/openssl-
    probe/releases/tag/0.2.0), and introduce a new `rust-openssl-probe0.1` compat package.

    Update `rust-rustls-native-certs` [to 0.8.3](https://github.com/rustls/rustls-native-
    certs/compare/v/0.8.2...v/0.8.3), now using `openssl-probe` 0.2.

    Update `rust-native-tls` [to 0.2.18](https://github.com/rust-native-tls/rust-native-
    tls/compare/v0.2.15...v0.2.18). Version 0.2.16 added TLS 1.3 as an option, added `stack_from_pem`, and
    upgraded `openssl-probe` to 0.2. Version 0.2.17 added support for ALPN on the server side. Version 0.2.18
    fixed min/max protocol selection fallback for very old OpenSSL versions.

    Add an initial package for `rust-webpki-root-certs`.
