rubygems-update fixed: 0.9.1 
Upgrade rubygems-update to 0.9.1
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 rubygems-update

How to Check if You Are Affected

To determine whether your application is affected by CVE-2007-0469, inspect your project dependencies for Rubygems update:

inspect dependencies for rubygems-update

Analyze the terminal output to locate any version of Rubygems update in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.1), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Rubygems update, 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

The `extract_files` function in `installer.rb` in RubyGems before 0.9.1 does not check whether files exist before overwriting them, which allows user-assisted remote attackers to overwrite arbitrary files, cause a denial of service, or execute arbitrary code via crafted GEM packages.
