BREW-MAILCATCHER-CVE-2012-6109 (GHSA-H77X-M5Q8-C29H)

Vulnerability from osv_homebrew – Published: 2026-08-13 17:11 – Updated: 2026-09-04 09:28 – Source website

Summary

Rack vulnerable to REDoS

Details

lib/rack/multipart.rb in Rack before 1.1.4, 1.2.x before 1.2.6, 1.3.x before 1.3.7, and 1.4.x before 1.4.2 uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.
