CVE-2007-0469: Rubyforge Rubygems

High severity, CVSS 9.3. EPSS: 4.8% chance of exploitation in the next 30 days.

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.

Affected products

• Rubyforge Rubygems: up to and including 0.9.0; version 0.8.11 only
