Rocky Linux 9.6 [TuxCare] Security Update: poppler / poppler-cpp / poppler-cpp-devel / poppler-devel / etc (ALMALINUX9.6:CLSA-2026:1775817651)

medium Nessus Plugin ID 361136

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1775817651 advisory.

 - 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 has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1775817651.
