Denial Of Service (DoS)

knot-resolver is vulnerable to denial of service. The vulnerability exists because of an algorithmic complexity which causes a memory consumption which allows an attacker to cause an application crash...

[SECURITY] Fedora 37 Update: bind-9.18.7-1.fc37

BIND Berkeley Internet Name Domain is an implementation of the DNS Domain Name System protocols. BIND includes a DNS server named, which resolves host names to IP addresses; a resolver library routines for applications to use when interfacing with DNS; and tools for verifying that the DNS server ...

Non-Responsive Delegation Attack' (NRDelegation Attack)

unbound:edge is vulnerable to non-responsive delegation attack. The attacker can cause a resolver to spend a lot of time/resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside...

Memory Leak

bind is vulnerable to memory leak. 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...
