CVE-2023-31124

Published: May 25, 2023

Modified: Feb 13, 2025

PUBLISHED

CVSS v3.1

3.7

LOW

Description

c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. This issue was patched in version 1.19.1.
