Multiple security issues were found in Rack, an interface for developing web applications in Ruby, which could result in denial of service, information disclosure, spoofing or bypass of access restrictions.

For the stable distribution (trixie), these problems have been fixed in version 3.1.20-0+deb13u2.

We recommend that you upgrade your ruby-rack packages.
