LibreOffice < 5.1.4 RTF Character Style Index RCE

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

An application installed on the remote host is affected by a remote
code execution vulnerability.

Description :

The version of LibreOffice installed on the remote Windows host is
prior to 5.1.4. It is, therefore, affected by a use-after-free error
during Rich Text Format (RTF) file parsing due to improper validation
of the RTF character style index. An unauthenticated, remote attacker
can exploit this, by convincing a user to open a specially crafted RTF
file, to execute arbitrary code.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.
