Astra Linux – Vulnerabilities in unbound, bind9, and 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 unbound

NLnet Labs Unbound, including version 1.16.1, is vulnerable to a new type of “ghost domain names” attack. The vulnerability operates by targeting an Unbound instance. When the cached delegation information is about to expire, Unbound queries for a rogue domain name. The rogue nameserver delays th...
