Synopsis

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

Description

The remote Fedora 45 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2026-852d99c4f2 advisory.

 - Update the zstd crate to version 0.14.3 and add a compat package for version 0.13.
 - Update the zstd-safe crate to version 8.2.0 and add a compat package for version 7.
 - Update the zstd-sys crate to version 2.1.2.

 This addresses multiple unsoundness and security issues in the zstd-safe and zstd-sys crates (assigned RUSTSEC-2026-0391, RUSTSEC-2026-0392, RUSTSEC-2026-0393, RUSTSEC-2026-0395, RUSTSEC-2026-0396, RUSTSEC-2026-0397, RUSTSEC-2026-0398, RUSTSEC-2026-0399, RUSTSEC-2026-0400, RUSTSEC-2026-0401, RUSTSEC-2026-0402, RUSTSEC-2026-0403, RUSTSEC-2026-0404, RUSTSEC-2026-0405, RUSTSEC-2026-0406).

 Rebuilds of affected applications will be tracked and performed separately.
