Who is Vulnerable?
Vulnerability Description	WordPerfect documents have common file extensions ".WP" and ".WPD", which is used by Corel's proprietary word processing application, WordPerfect. Its popularity was based on the fact that it had been available for a wide variety of computers and operation systems, including Mac OS, Linux, and other Unix like systems. There exists a buffer overflow vulnerability in the open source WordPerfect Document Importer/Exporter (libwpd) library. The flaw is due to improper boundary check when processing crafted WordPerfect documents. An attacker can exploit this vulnerability by persuading a victim to open a specially crafted WordPerfect (WPD) document. Successful exploitation of this vulnerability may lead to arbitrary code execution in the context of the currently logged in user. In an attack scenario, where arbitrary code is attempted to be injected and executed on the target machine, the behaviour of the target is dependent on the intention of the malicious code. If such an attack fails to execute successfully, the application using the vulnerable component may terminate as a result of the exploitation.
