Produktbeschreibung: OpenLDAP ist eine frei verfügbare Implementierung des Verzeichnisdienstes LDAP.
Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in OpenLDAP ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux - Windows
CVE-2020-12243

In OpenLDAP besteht eine Schwachstelle aufgrund einer fehlenden Begrenzung bei der Verarbeitung von Filterausdrücken in [filter.c]. Ein entfernter Anonymer kann eine speziell gestaltete Anfrage mit einem übermäßig langen und verschachtelten Suchausdruck senden und damit den "slapd"-Prozess zum Absturz bringen.
