NLnet Labs Unbound up to and including version 1.25.0 has a vulnerability in the jostle logic that could defeat its purpose and degrade resolution… (CVE-2026-42534)CVE-2026-42534 0 NLnet Labs Unbound up to and including version 1.25.0 contains a vulnerability in its jostle logic that can degrade DNS resolution performance. The flaw allows retransmitted duplicate queries to reset the aging timer of slow queries, preventing their replacement and potentially causing denial of resolution service under coordinated attack. Cache and local data responses are not affected. Unbound 1.25.1 includes a patch that fixes this by attaching a fixed start time to queries, enabling proper aging and replacement logic.

NLnet Labs Unbound up to and including version 1.25.0 is vulnerable to a degradation of service attack related to parsing long lists of incoming… (CVE-2026-41292)CVE-2026-41292 0 NLnet Labs Unbound versions up to and including 1.25.0 are vulnerable to a denial of service condition caused by processing excessive EDNS options in DNS queries. Attackers can send queries with too many EDNS options, causing Unbound threads to be held up while parsing and building internal data structures, leading to degraded service or denial of service. Version 1.25.1 includes a fix that limits the number of acceptable incoming EDNS options to 100. Red Hat has released security advisories and updated packages addressing this vulnerability for their hardened images and Red Hat Enterprise Linux 10 distributions.
