CVE-2026-42944
NLnet Labs Unbound 1.14.0–1.25.0 is affected by a heap overflow when encoding multiple NSID and/or DNS Cookie EDNS and/or EDNS Padding options in replies. The vulnerability requires the options (nsid, answer-cookie, pad-responses) to be enabled, and a querier can trigger the overflow by attaching...
CVE-2026-42923
NLnet Labs Unbound up to and including version 1.25.0 has a vulnerability in the DNSSEC validator where the code path to consult the negative cache for DS records does not take into account the limit on NSEC3 hash calculations introduced in 1.19.1. This leads to degradation of service during the...
Astra Linux – Vulnerability in bind9
The DNS message parsing code in named includes a section whose computational complexity is excessively high. This does not cause problems for typical DNS traffic, but crafted queries and responses may lead to excessive CPU load on the affected named instance by exploiting this flaw. This issue...
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 connman
