Summary

Apache OpenOffice through 4.1.16 accepts extraneous untrusted data alongside trusted data (CWE-349), so a manipulated document can display substituted content that differs depending on the program used to open it. An attacker needs a user to open a manipulated document, and the source states that such documents are corrupt and should not be opened.
