CVE-2022-30122: Prevent a Denial of Service (DoS) vulnerability in the HTTP multipart parsing.

For Debian 10 buster, these problems have been fixed in version 2.0.6-3+deb10u1.

We recommend that you upgrade your ruby-rack packages.

For the detailed security status of ruby-rack please refer to its security tracker page at: [link moved to references]
