Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-3592)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper handling of self-pointed glue records in BIND resolver processing when resolving names in a specially crafted zone. A remote attacker can induce the resolver to query a specially crafted zone to cause a denial of service.

The issue predominantly affects recursive resolvers. Authoritative-only servers containing only trustworthy zones and names are believed to be unaffected.
