[Salvatore Bonaccorso]

Source: puma
Version: 5.6.5-4

Hi,

The following vulnerability was published for puma.

CVE-2023-40175[0]:
| 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.
