CVE-2026-69184

A flaw was found in c-ares, an asynchronous resolver library. The 'aresdnsnameparse' function does not properly limit the total pointer hops or assembled name length when enforcing backward DNS compression pointers. A remote attacker, operating a malicious DNS server, can send a specially crafted...

AZL-103307 CVE-2026-69184 affecting package c-ares 1.30.0-2

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsnameparse enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource...

CVE-2026-69184

c-ares (asynchronous DNS resolver library) prior to 1.34.7 is affected by a CPU-exhaustion denial-of-service in ares_dns_name_parse(). The function enforces backward DNS compression pointers but does not bound total pointer hops or assembled name length, so a malicious DNS server can send a respo...
