Description Marian Rehak 2022-09-21 08:42:41 UTC 
The DNSSEC verification code for the ECDSA algorithm leaks memory when there is a signature length mismatch. By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.
