CVE-2017-3157

By exploiting the way Apache OpenOffice before 4.1.4 renders embedded
objects, an attacker could craft a document that allows reading in a file
from the user’s filesystem. Information could be retrieved by the attacker
by, e.g., using hidden sections to store the information, tricking the user
into saving the document and convincing the user to send the document back
to the attacker. The vulnerability is mitigated by the need for the
attacker to know the precise file path in the target system, and the need
to trick the user into saving the document and sending it back.
