Linux Distros Unpatched Vulnerability : CVE-2025-54869

medium Nessus Plugin ID 253368

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - FPDI is a collection of PHP classes that facilitate reading pages from existing PDF documents and using them as templates in FPDF. In versions 2.6.2 and below, any application that uses FPDI to process user- supplied PDF files is at risk, causing a Denial of Service (DoS) vulnerability. An attacker can upload a small, malicious PDF file that will cause the server-side script to crash due to memory exhaustion.
 Repeated attacks can lead to sustained service unavailability. This issue is fixed in version 2.6.3.
 (CVE-2025-54869)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
