Title
Out-of-bounds read when parsing DNS packets via Lua
Summary
An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential information disclosure.

Vulnerability from csaf_certbund - Published: 2026-03-30 22:00 - Updated: 2026-04-28 22:00Summary
PowerDNS: Mehrere Schwachstellen
Severity
Hoch
Notes
Das BSI ist als Anbieter für die eigenen, zur Nutzung bereitgestellten Inhalte nach den allgemeinen Gesetzen verantwortlich. Nutzerinnen und Nutzer sind jedoch dafür verantwortlich, die Verwendung und/oder die Umsetzung der mit den Inhalten bereitgestellten Informationen sorgfältig im Einzelfall zu prüfen.
Produktbeschreibung: Der Domain Name Service (DNS) ermöglicht die Umsetzung der Domainnamen in IP-Adressen. Zur Verhinderung von übermäßigen Anfragen werden die Zuordnungen häufig lokal in einem Cache gespeichert.
Angriff: Ein Angreifer kann mehrere Schwachstellen in PowerDNS ausnutzen, um Informationen offenzulegen, Sicherheitsmaßnahmen zu umgehen, um einen Denial of Service zu verursachen und potentiell Code auszuführen.
Betroffene Betriebssysteme: - Linux
- Sonstiges
- UNIX
