Amazon Linux 2023 : cargo, clippy, rust (ALAS2023-2026-1951)

high Nessus Plugin ID 328502

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1951 advisory.

 gix-submodule before 0.29.0 (gitoxide before 0.5.21, gix before 0.84.0) incorrectly validates the update field in .gitmodules, allowing attackers to bypass the CommandForbiddenInModulesConfiguration guard when a submodule has been initialized with only partial configuration in .git/config. An attacker can inject arbitrary shell commands via the update field in .gitmodules that will be executed when Submodule::update() is called on a previously-initialized submodule, enabling remote code execution.
 (CVE-2026-40034)

 gitoxide before 0.52.1 follows symlinks when reading the worktree .gitmodules file, allowing attackers to inject out-of-repository bytes into submodule metadata. Attackers can create a malicious repository with a symlinked .gitmodules pointing outside the repository tree, causing gitoxide to parse arbitrary external files as submodule configuration and expose attacker-controlled name, path, and url values.
 (CVE-2026-82252)

 gitoxide before 0.69.0 contains unchecked array indexing in delta application and uncapped allocation from attacker-controlled size headers in gix-pack. Attackers can send crafted pack data during clone or fetch operations to trigger panics or out-of-memory process kills. (CVE-2026-82254)

 gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects. The vulnerability occurs because credential validation checks the original URL instead of the effective URL after redirect, allowing attackers to steal authentication tokens through cross-domain redirects or HTTPS-to-HTTP downgrades. (CVE-2026-82255)

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update rust --releasever 2023.12.20260720' or or 'dnf update --advisory ALAS2023-2026-1951 --releasever 2023.12.20260720' to update your system.
