How to Fix CVE-2019-16139

To remediate this vulnerability, upgrade all affected Compact arena dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

compact_arena fixed: 0.4.0 
Upgrade compact_arena to 0.4.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for compact_arena

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-16139, inspect your project dependencies for Compact arena:

inspect dependencies for compact_arena

Analyze the terminal output to locate any version of Compact arena in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Compact arena, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions of this crate did not properly implement the generativity, because the invariant lifetimes were not necessarily dropped. This allows an attacker to mix up two arenas, using indices created from one arena with another one. This might lead to an out-of-bounds read or write access into the memory reserved for the arena. The flaw was corrected by implementing generativity correctly in version 0.4.0.
