WPS Office (an acronym for Writer, Presentation and Spreadsheets,[2] previously known as Kingsoft Office) is an office
|
|
|
|
suite for Microsoft Windows, Linux,[1] iOS[3] and Android OS,[4] developed by Zhuhai-basedChinese software developer Kingsoft.
|
|
|
|
WPS Office is a suite of software which is made up of three primary components: WPS Writer, WPS Presentation, and WPS Spreadsheet.
|
|
|
|
The personal basic version is free to use, but a watermark is printed on all printed output after the 30 day trial ends.

3) Technical details
|
|
============================
|
|
|
|
The specific flaw exists within the handling of a crafted PPT files with an invalid value into “texttype” in the “clientTextBox”
|
|
into a “DrawingContainer”. An heap memory corruption occured and could allow remote attackers to execute arbitrary code
|
|
on vulnerable installations of WPS. User interaction is required to exploit this vulnerability, the target must open a malicious file.
