How to Fix CVE-2014-10077

To remediate this vulnerability, upgrade all affected I18n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

i18n fixed: 0.8.0 
Upgrade i18n to 0.8.0
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 i18n

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-10077, inspect your project dependencies for I18n:

inspect dependencies for i18n

Analyze the terminal output to locate any version of I18n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.0), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In I18n, 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

Hash#slice in lib/i18n/core_ext/hash.rb in the i18n gem before 0.8.0 for Ruby allows remote attackers to cause a denial of service (application crash) via a call in a situation where :some_key is present in keep_keys but not present in the hash.
