Summary

libconfuse security update

Details

libConfuse is a configuration file parser library, licensed under the terms of the ISC license, and written in C. It supports sections and (lists of) values (strings, integers, floats, booleans or other sections), as well as some other features (such as single/double-quoted strings, environment variable expansion, functions and nested include statements). It makes it very easy to add configuration file capability to a program using a simple API. The goal of libConfuse is not to be the configuration file parser library with a gazillion of features. Instead, it aims to be easy to use and quick to integrate with your code.

Security Fix(es):

cfg_tilde_expand in confuse.c in libConfuse 3.3 has a heap-based buffer over-read.(CVE-2022-40320)

Severity

8.8 (High)
