CVE-2022-38178

A flaw was found in the Bind package, where the DNSSEC verification code for the EdDSA algorithm leaks memory when there is a signature length mismatch. By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak, resulting in...

CVE-2022-3080

A flaw was found in the Bind package, where the resolver can crash when stale cache and stale answers are enabled, option stale-answer-client-timeout is set to 0 and there is a stale CNAME in the cache for an incoming query. By sending specific queries to the resolver, an attacker can cause named...
