Linux Distros Unpatched Vulnerability : CVE-2025-4035

medium Nessus Plugin ID 244936

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.

- A flaw was found in libsoup. When handling cookies, libsoup clients mistakenly allow cookies to be set for public suffix domains if the domain contains at least two components and includes an uppercase character.
This bypasses public suffix protections and could allow a malicious website to set cookies for domains it does not own, potentially leading to integrity issues such as session fixation. (CVE-2025-4035)

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

Solution

There is no known solution at this time.
