Es wurden Korrekturversionen der Datenbank-Management-Systeme Redis (6.2.19, 7.2.10, 7.4.5, 8.0.3) und Valkey (8.0.4, 8.1.3) ver\u00f6ffentlicht, in denen zwei Sicherheitsanf\u00e4lligkeiten behoben wurden. Die gef\u00e4hrlichste Sicherheitsanf\u00e4lligkeit (CVE-2025-32023) k\u00f6nnte potenziell zu einer Ausf\u00fchrung von entferntem Code auf dem Server f\u00fchren, da Daten in Bereiche au\u00dferhalb des zugewiesenen Puffers geschrieben werden. Um die Sicherheitsanf\u00e4lligkeit auszunutzen, muss der Angreifer in der Lage sein, Befehle an das Datenbank-Management-System zu senden. <\/p>\n

Das Problem wird durch einen Fehler in der Implementierung von Befehlen verursacht, die den HyperLogLog-Algorithmus zur ungef\u00e4hren Z\u00e4hlung einzigartiger Elemente in einer Menge verwenden. Durch das \u00dcbermitteln einer speziell gestalteten Zeichenfolge kann der Angreifer ein Puffer\u00fcberlauf ausl\u00f6sen. Das Problem betrifft alle Redis-Versionen, die HLL-Befehle unterst\u00fctzen. Als Workaround zur Abwehr kann der Zugriff der Benutzer auf die HLL-Befehle \u00fcber ACL eingeschr\u00e4nkt werden. <\/p>\n

Die zweite Sicherheitsanf\u00e4lligkeit (CVE-2025-48367) kann von einem authentifizierten Benutzer ausgenutzt werden, um einen Denial-of-Service-Angriff zu initiieren oder die Leistung des Datenbank-Management-Systems zu beeintr\u00e4chtigen. Das Problem wird durch eine unzureichende Fehlerbehandlung bei der Herstellung von Verbindungen verursacht.
