Linux Distros Unpatched Vulnerability : CVE-2025-52886

medium Nessus Plugin ID 252239

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.

 - Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue. (CVE-2025-52886)

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

Solution

There is no known solution at this time.
