CVE-2023-31130

Description

A vulnerability was found in c-ares. This issue occurs in the ares_inet_net_pton() function, which is vulnerable to a buffer underflow for certain ipv6 addresses. "0::00:00:00/2" in particular was found to cause an issue. C-ares only uses this function internally for configuration purposes, which would require an administrator to configure such an address via ares_set_sortlist().

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
