Ubuntu 23.04 : Puma vulnerability (USN-6399-1)

critical Nessus Plugin ID 181943

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 23.04 host has a package installed that is affected by a vulnerability as referenced in the USN-6399-1 advisory.

 - Puma is a Ruby/Rack web server built for parallelism. Prior to versions 6.3.1 and 5.6.7, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in a way that allowed HTTP request smuggling. Severity of this issue is highly dependent on the nature of the web site using puma is. This could be caused by either incorrect parsing of trailing fields in chunked transfer encoding bodies or by parsing of blank/zero-length Content-Length headers. Both issues have been addressed and this vulnerability has been fixed in versions 6.3.1 and 5.6.7. Users are advised to upgrade.
 There are no known workarounds for this vulnerability. (CVE-2023-40175)

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.
