  - A security vulnerability has been detected in Kamailio 5.5. Impacted is the function rve_destroy of the
    file src/core/rvalue.c of the component Configuration File Handler. The manipulation leads to heap-based
    buffer overflow. The attack must be carried out locally. The exploit has been disclosed publicly and may
    be used. There is ongoing doubt regarding the real existence of this vulnerability. This attack requires
    manipulating config files which might not be a realistic scenario in many cases. The vendor was contacted
    early about this disclosure but did not respond in any way. (CVE-2025-12204)

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