Produktbeschreibung: Mit poppler können PDF-Dokumente unter Unix-ähnlichen Betriebssystemen betrachtet werden.

Angriff: Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in poppler ausnutzen, um einen Denial of Service Angriff durchzuführen.

Betroffene Betriebssysteme: - UNIX - Linux

CVE-2018-20481

In poppler existieren mehrere Schwachstellen. Diese bestehen in Fehlern bei der Behandlung von Eingaben in [Parser.cc] wenn "XRefEntry::setFlag" in [XRef.h] von "Parser::makeStream" aufgerufen wird und "AnnotRichMedia" class in [Annot.c]. Ein Angreifer kann diese Schwachstellen durch Übermittlung geiegnet gestalteter Daten zu einem Denial of Service Angriff nutzen. Zur erfolgreichen Ausnutzung dieser Schwachstelle muss der Angreifer den Benutzer dazu bringen, eine modifizierte Datei zu öffnen.
