gsd-2022-38178
Vulnerability from gsd
Modified
2023-12-13 01:19
Details
By spoofing the target resolver with responses that have a malformed EdDSA 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.
