Astra Linux – vulnerability in unbound, bind9, dnsmasq

Certain DNSSEC aspects of the DNS protocol as defined in RFC 4033, 4034, 4035, 6840, and related RFCs enable remote attackers to induce a denial of service due to excessive CPU usage by sending one or more DNSSEC responses; this issue is known as “KeyTrap”. One concern is that when a zone contain...

Astra Linux – vulnerability in bind9

By spoofing the target resolver with responses containing a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually deplete available memory until it reaches a point where crashes occur due to insufficient resources...

Astra Linux – vulnerability in bind9

It is possible to create a zone such that certain queries directed to it produce responses containing numerous records within the Additional section. An attacker sending multiple such queries can cause either the authoritative server itself or an independent resolver to expend disproportionately...

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 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...

Security Bulletin:Vulnerability in BIND 9 affects IBM Netezza Appliance

Summary The BIND 9 package is used by IBM Netezza Appliance. IBM Netezza Appliance has addressed the applicable CVE CVE-2026-5946 Vulnerability Details CVEID:CVE-2026-5946 DESCRIPTION: Multiple flaws have been identified in named related to the handling of DNS messages whose CLASS is not Internet...

SUSE CVE-2026-11331

An attacker who knows or guesses that a resolver uses RPZ with wildcard CNAME policies can craft query names long enough to trigger a NAMETOOLONG error condition during RPZ processing. This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an unexpected exit of...

SUSE CVE-2026-11622

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

SUSE CVE-2026-12617

The issue is unexpected program termination based on ordering and/or specific content in responses to queries for CNAME or DNAME, and A records. Specifically, if a client queries for a DNAME and A record below the DNAME to the resolver, and the authoritative server responds positively to the A...

CVE-2026-11721

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...
