Fedora 44 : perl-HTTP-Daemon (2026-8982379b5c)

critical Nessus Plugin ID 321631

Synopsis

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

Description

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-8982379b5c advisory.

 Changes:

 6.17 2026-05-19 23:11:06Z

 - Fix CVE-2026-8450 (affects 6.15 and earlier): 2-arg open() in send_file() enabled RCE / arbitrary file write / response-body exfiltration when a string argument was derived from attacker- influenced input. send_file() now uses 3-arg open() with an explicit '<' read mode, so the path is always treated as a literal filename and 2-arg open() shell-magic shapes ('| cmd', 'cmd |', '> path', etc.) are no longer interpreted. send_file() now also returns '0E0' (true zero) on a successful zero-byte transfer so callers can distinguish empty file from open failure (undef). See https://www.cve.org/CVERecord?id=CVE-2026-8450 for the advisory.
 Reported and patched by Stig Palmquist (stigtsp). (Stig Palmquist, Olaf Alders)
