CVE-2026-3592

BIND resolvers are vulnerable to an amplified resource consumption/exhaustion attack. If a victim resolver makes a query to a specially crafted zone, the resolver will consume disproportionate resources. This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.48, 9.20.0...

Astra Linux – Vulnerability in bind9

Resolver caches and authoritative zone databases that hold a significant number of Resource Records for the same hostname of any RTYPE may experience degraded performance as content is added or updated, as well as when handling client queries for this name. This issue affects BIND 9 versions 9.11...

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...

Astra Linux – Vulnerability in bind9

The code that processes control channel messages sent to named recursively calls certain functions during packet parsing. The recursion depth is limited only by the maximum acceptable packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack...

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 – 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...
