Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in c-ares. This issue occurs 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. As a result, it will downgrade to rand(), which could allow an attacker to utilize the lack of entropy by not using a CSPRNG.

Description Sandipan Roy 2023-05-24 03:43:06 UTC 
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.

CVE-2023-31124. Low. AutoTools does not set CARES_RANDOM_FILE during cross compilation (https://github.com/c-ares/c-ares/security/advisories/GHSA-54xr-f67r-4pc4)
