Vulnerability ID VCID-vmy4-5p4s-mbec
Aliases CVE-2023-31124
GHSA-54xr-f67r-4pc4
Summary Use of Insufficiently Random Values 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.
