Ubuntu 23.04 / 23.10 : Puma vulnerability (USN-6597-1)

high Nessus Plugin ID 189520

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 23.04 / 23.10 host has a package installed that is affected by a vulnerability as referenced in the USN-6597-1 advisory.

 - Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, puma exhibited 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. This vulnerability has been fixed in versions 6.4.2 and 5.6.8. (CVE-2024-21647)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected puma package.
