Beschreibung:
Einige Sicherheitslücken in IBM Lotus Notes wurden gemeldet, die böswillige Personen ausnutzen können, um das System eines Benutzers zu kompromittieren.

Die Sicherheitslücken bestehen aufgrund von Begrenzungsfehlern innerhalb des "Lotus 1-2-3"-Dateibetrachters (l123sr.dll) und können ausgenutzt werden, um Pufferüberlaufe zu verursachen, indem man einen Benutzer dazu bringt, einen speziell präparierten "Lotus 1-2-3"-Anhang zu betrachten, der z.B. einen speziell präparierten "SRANGE" Eintrag enthält.

Eine erfolgreiche Ausnutzung könnte die Ausführung von beliebigem Code ermöglichen.

Die Sicherheitslücken wurden in Versionen 7.0 und 8.0 gemeldet.
