CVE-2023-31124

AutoTools does not set CARES_RANDOM_FILE during cross compilation

Published: May 25, 2023Updated: Feb 13, 2025 Sources: CVE List NVD BDU csafCWE-330

3.7LOW

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.
