Fedora 45 : perl-Plack / perl-Plack-Middleware-ReverseProxy (2026-04e2968a8a)

critical Nessus Plugin ID 374620

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 45 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-04e2968a8a advisory.

 A number of security issues were found in the Plack stack:
 SECURITY Fix memory leak of every request env in Plack::Middleware::Recursive (CVE-2026-110333) Plack::Request::Upload->basename never returns '', '.' or '..' (CVE-2026-110332) Plack::App::URLMap matches SERVER_PORT literally when stripping it from Host (CVE-2026-110335) BUG FIXES Plack::Middleware::ErrorDocument restores the env after a subrequest, so outer middleware such as AccessLog sees the original request (CVE-2026-110334) DOCUMENTATION Document that Plack::Handler::FCGI and Apache2 keep dot segments in PATH_INFO and warn against relying on front-server path-based access control (CVE-2026-110336)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

Solution

Update the affected perl-Plack and / or perl-Plack-Middleware-ReverseProxy packages.
