Common Weakness Enumeration
CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
12190 vulnerabilities reference this CWE, most recent first.

Summary
Use-after-free when setting the locale
Details
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.

Mitigation
Architecture and Design
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Implementation
Strategy: Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
No CAPEC attack patterns related to this CWE.
