    Package        : ruby-rack
    Version        : 2.0.6-3+deb10u1
    CVE ID         : CVE-2022-30122 CVE-2022-30123

    Two vulnerabilities were discovered in `ruby-rack`, a popular Ruby
    webserver:

    CVE-2022-30122:

        Prevent a Denial of Service (DoS) vulnerability in the HTTP
        multipart parsing.

    CVE-2022-30123:

        Prevent a potential shell escape sequence injection
        vulnerability that could be triggered through the logging system.

    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.
