Astra Linux – Vulnerabilities in unbound, bind9, dnsmasq

Certain aspects of the DNS protocol’s DNSSEC mechanism described in RFC 4033, 4034, 4035, 6840, and related RFCs allow remote attackers to cause a denial of service attack by manipulating one or more DNSSEC responses. This issue is known as the “KeyTrap” problem. One of the concerns is that, when...

Astra Linux – Vulnerability in bind9

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 the available memory to the point where named crashes occur due to lack of resources...

Astra Linux – Vulnerability in bind9

By flooding the target resolver with queries that exploit this flaw, an attacker can significantly impair the resolver’s performance, effectively denying legitimate clients access to the DNS resolution service...
