CVE-2026-69186
A flaw was found in c-ares, an asynchronous resolver library. A remote attacker can send a specially crafted DNS response that causes the aresdnsparse function to trust attacker-controlled record counts without validating if the response contains enough bytes for the claimed records. This can lea...
CVE-2026-69186
c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsparse trusts the attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT fields before confirming that the DNS response contains enough bytes for the claimed records. Because processanswer invokes parsing before transaction ID and...
