CVE-2023-31124 Information

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.
