GHSA-3JWC-8HP9-37FW

Vulnerability from github – Published: 2024-08-12 15:30 – Updated: 2025-11-04 00:31

Details

A heap-buffer-overflow flaw was found in the cfg_mark_ports function within Unbound's config_file.c, which can lead to memory corruption. This issue could allow an attacker with local access to provide specially crafted input, potentially causing the application to crash or allowing arbitrary code execution. This could result in a denial of service or unauthorized actions on the system.

Severity ?

4.8 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L
