Produktbeschreibung: Dovecot ist ein Open Source IMAP und POP3 E-Mail Server.
Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Dovecot ausnutzen, um beliebigen Programmcode mit den Rechten des Dienstes auszuführen oder um Informationen offenzulegen.
Betroffene Betriebssysteme: - Linux
CVE-2019-11500

In Dovecot besteht eine Schwachstelle in den Protokoll-Parsern für IMAP und ManageSieve. Bei der Verarbeitung eingehender Pakete werden "NUL" Bytes nicht ordnungsgemäß behandelt. Dadurch kann ein "out-of-bounds" Schreib- oder Lesezugriff auf dem Heap-Speicher ausgelöst werden. Ein entfernter anonymer Angreifer kann dies ausnutzen, um Informationen offenzulegen oder um beliebigen Code mit den Rechten des Dienstes auszuführen.
