    Package        : puma     Version        : 4.3.8-1+deb11u3     CVE ID         : CVE-2024-21647 CVE-2024-45614


    Two vulnerabilities have been fixed in puma, a threaded HTTP server     for Ruby/Rack applications.

    CVE-2024-21647

        Incorrect behavior when parsing chunked transfer encoding bodies         in a way that allowed HTTP request smuggling. Fixed versions         limits the size of chunk extensions. Without this limit, an         attacker could cause unbounded resource (CPU, network bandwidth)         consumption.

    CVE-2024-45614

        Clients could clobber values set by intermediate proxies (such as         X-Forwarded-For) by providing a underscore version of the same         header (X-Forwarded_For). Any users relying on proxy set variables         is affected.

    For Debian 11 bullseye, these problems have been fixed in version     4.3.8-1+deb11u3.

    We recommend that you upgrade your puma packages.
