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

For the oldstable distribution (bookworm), these problems have been fixed
in version 2.2.20-0+deb12u1.

For the stable distribution (trixie), these problems have been fixed in
