Internet Systems Consortium BIND: Mehrere Schwachstellen
WID-SEC-2026-2484 · first 23.07.2026 · updated 15.10.2026 · CVSS 8,6
What it is about
BIND (Berkeley Internet Name Domain) ist ein Open-Source-Softwarepaket, das einen Domain-Name-System-Server implementiert. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Internet Systems Consortium BIND ausnutzen, um Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand auszulösen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren
- vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand auszulösen
Am I affected?
Affected according to the BSI:
- Debian Linux
- Amazon Linux 2
- Red Hat Enterprise Linux
- Fedora Linux
- IBM AIX
- Red Hat OpenShift Container Platform
- F5 BIG-IP
- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
- Ubuntu Linux
- Oracle Linux
and 6 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Internet Systems Consortium BIND 9.20.26
- Internet Systems Consortium BIND 9.21.24
- Internet Systems Consortium BIND Supported Preview Edition 9.20.26-S1
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
