Use-after-free when setting the locale

Moderate severity GitHub Reviewed Published Jan 23, 2024 to the GitHub Advisory Database • Updated Jan 23, 2024

Package

cargo rust-i18n-support (Rust)

Affected versions

>= 3.0.0, < 3.0.1

Patched versions

3.0.1

Description

Version 3.0.0 introduced an AtomicStr type, that is used to store the current locale. It stores the locale as a raw pointer to an Arc<String>. The locale can be read with AtomicStr::as_str(). AtomicStr::as_str() does not increment the usage counter of the Arc.

If the locale is changed in one thread, another thread can have a stale -- possibly already freed -- reference to the stored string.
