Amazon Linux 2023 Security Advisory: ALAS2023-2026-1951
Advisory Released Date: 2026-07-20
Advisory Updated Date: 2026-07-20
Severity:
Important
Issue Overview:
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)
Affected Packages:
rust
Issue Correction:
Run dnf update rust --releasever 2023.12.20260720 or dnf update --advisory ALAS2023-2026-1951 --releasever 2023.12.20260720 to update your system.
More information on how to update your system can be found on this page: Amazon Linux 2023 documentation
