CVE-2023-31124
May 25, 2023
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.
Affected Packages
c-ares (CONAN):
Affected version(s) >=1.14.0 <1.19.1
Fix Suggestion:
Update to version 1.19.1
Additional Notes
The description of this vulnerability differs from MITRE.
