LibreOffice 3.3 'Lotus Word Pro' document import filter contains multiple vulnerabilities

Overview

LibreOffice 3.3.2 includes a feature to import 'Lotus Word Pro' (.lwp) documents. This import filter contains multiple vulnerabilities. CERT/CC has confirmed that code execution is possible by exploiting a stack buffer overflow.

I. Description

LibreOffice 3.3.2, 3.3.1, and possibly earlier versions fail to properly handle 'Lotus Word Pro' (.lwp) documents. The (.lwp) format is the native file format for Lotus Word Pro that is a word processor developed by IBM's Lotus Software group. More details can be found by reviewing the following patch commits: Commit 1 and Commit 2.

II. Impact

By convincing a user to open a specifically crafted 'Lotus Word Pro' (.lwp) document, an attacker may be able to execute arbitrary code.

III. Solution

Apply an Update

LibreOffice 3.3.3 and 3.4.0 both address these vulnerabilities.
